Description

Technical Field

[0001] The present invention relates to the field of piezoelectric film sensors, and further to a multi-point micro-force sensitive sensor, an in-body muscle strength detection device and applications thereof. Background Art

[0002] Piezoelectric film sensors, also known as pressure film sensors or film pressure sensors, are dynamic strain sensors that can detect dynamic stress. They are very suitable for life signal detection on the surface of human skin or implanted in the human body. Some piezoelectric film elements are sensitive enough to detect the beating of the human pulse through the coat. General piezoelectric materials are sensitive to pressure, but for piezoelectric films, when a small force is applied longitudinally, a large stress will be generated in the lateral direction. If the same force is applied to a large area of ​​the film, the stress generated will be much smaller. Therefore, piezoelectric film sensors are very sensitive to dynamic stress. The typical sensitivity of 28μm thick PVDF is 10-15mV / microstrain (parts per million change in length).

[0003] Therefore, the piezoelectric film sensor is usually used in detection equipment such as stethoscopes, heartbeat detection equipment, respiratory monitors, in-body muscle strength detection equipment or Kegel medical exercise equipment and other medical equipment. It can effectively detect human motion characteristics such as heartbeat, breathing, targeted exercise feedback, muscle recovery strength, postoperative rehabilitation indicators, etc.

[0004] For some in-body muscle strength detection devices such as Kegel trainers or male prostate rehabilitation devices, they need to be placed inside the human body's cavities such as the female reproductive tract cavity, pelvic cavity, urethral cavity or anal cavity or the male urethral cavity, anal cavity, pelvic cavity, etc., wherein the piezoelectric film sensor is arranged on the surface of the in-body muscle strength detection device. During operation, the piezoelectric film sensor can directly or indirectly receive the force exerted by the male or female pelvic floor muscle group or sphincter group or pubococcygeus muscle group, and convert it into a series of electrical signals and transmit it to the user end, so that the user or doctor can obtain the feedback results of the massage, training or rehabilitation process to help the user's rehabilitation training or massage schedule.

[0005] Normally, a piezoelectric film sensor is composed of a plurality of micro-force sensitive detection units connected in series or in parallel, each of which has a certain detection area or area, and these piezoelectric film units are connected in series or in parallel to form an integral piezoelectric film sensor, wherein the more the number of the micro-force sensitive detection units is, the higher the detection accuracy of the piezoelectric film sensor is. However, in the current structure, the plurality of micro-force sensitive detection units are usually arranged horizontally, vertically or unidirectionally on the surface of the detection device, that is, each of the detection areas is arranged horizontally, vertically or unidirectionally, but since the size of the detection device has certain specifications, that is, the sum of the widths of each of the micro-force sensitive detection units is less than the width of the operating area on the surface of the detection device, the number of the piezoelectric film units is limited by the width of the operating area of ​​the detection device, and thus more piezoelectric film units cannot be arranged, that is, the micro-force sensitive detection units can only be arranged in the same direction in the effective working area of ​​the detection device, resulting in low detection accuracy.

[0006] It can be seen that each sub-detection area corresponds to a micro-force-sensitive detection unit, which makes the detection value of each sub-detection area single, and the precise contrast is too low, making the detection accuracy low. In addition, when any of the micro-force-sensitive detection units is damaged, the sub-detection area cannot continue to detect and loses part of the data, resulting in interruption or error of the algorithm data chain of the piezoelectric film sensor, etc., and it cannot be used anymore, and even misleads the doctor's diagnosis or the user's exercise or massage plan.

[0007] In addition, when the micro-force-sensitive detection unit is arranged in the detection device, each piezoelectric film unit needs to be supported by the shell of the detection device to form a stable working area to ensure the sensitivity and safety of the sensing area. Accordingly, each micro-force-sensitive detection unit is installed at intervals from each other, which wastes the working area of ​​the detection device surface, and thus it is impossible to install more micro-force-sensitive detection units, so that the sensing accuracy cannot be improved.

[0008] Generally, the piezoelectric film sensor is installed on the surface of the detection device, wherein the detection element of the piezoelectric film sensor is arranged on the surface of the detection device to receive and detect the external force on the surface of the detection device. When the external force is large or the force is applied for a long time, the detection sensitivity of the detection element of the piezoelectric film sensor may decrease or even be damaged, reducing the service life.

[0009] In particular, the muscles in the human body cavity, such as the pelvic floor muscles, have relatively complex muscle tissues, and the pressure generated by the muscles at certain locations is relatively small, which is generally referred to as micro-muscle force. Since the pressure of these micro-muscle forces is relatively small, the electrical signals output by existing detection equipment are relatively weak, and it is even difficult to output them as electrical signals, thereby losing the output of the detection signals for some or all of the micro-muscle forces, making the detection results insensitive, and unable to obtain the subtle force changes of certain muscles of the pelvic floor muscles in a more detailed manner, making the detection results unreliable. Similarly, the detection equipment cannot provide users or doctors with specific feedback information on these micro-forces, which is not conducive to the user's exercise or rehabilitation training or the doctor's diagnosis.

The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0083] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0084] The present invention provides a multi-point micro-force sensor, an in-body muscle force detection device and its application, which is applied to a detection device, wherein the detection device is, for example, an in-body muscle force detection device or a medical or exercise massage device such as a Kegel medical exercise device, but not limited thereto, wherein the detection device is generally applicable to a human body or an animal body, so as to obtain relevant detection information by detecting pressure changes, and to help a human body or an animal body complete physiological detection, postoperative recovery, health physiotherapy or massage relaxation, etc. or a series of action operations. It can collect the muscle micro-force of one or more points in a cavity of the user, such as the muscle micro-force of multiple points of the pelvic floor muscle, and calculate the magnitude of one or more of the above-mentioned muscle micro-forces through an amplification circuit or a microcontroller unit (MCU), and can be fed back as the vibration intensity of one or more vibration motors corresponding to the above-mentioned multiple points, or the intensity of the corresponding flashing of one or more lights, or presented as a graphic change of one or more images on a user end, etc., to enhance the user experience, or visualize the detection results so that the user or doctor can see them intuitively, and facilitate the next exercise or rehabilitation adjustment.

[0085] In the present invention, the detection device is implemented as an in-body muscle strength detection device such as a Kegel trainer or a male prostate rehabilitation device, wherein the in-body muscle strength detection device is used to be placed in a human body cavity to complete pressure detection operations, such as a female reproductive tract cavity, pelvic cavity, urethral cavity or anal cavity or a male urethral cavity, anal cavity, pelvic cavity, etc., wherein the multi-point micro-force sensitive sensor is arranged on the surface of the in-body muscle strength detection device, and the maximum number of micro-force sensitive detection units can be arranged in the effective working area of ​​the detection device surface to improve the detection accuracy. During operation, the multi-point micro-force sensitive sensor can directly or indirectly receive the force applied by the male or female pelvic floor muscle group or sphincter group or pubococcygeus muscle group, and convert it into a series of electrical signals and transmit it to the user end, so that the user or doctor can obtain the feedback results of the massage, training or rehabilitation process to help the user's rehabilitation training, rehabilitation status or massage schedule.

[0086] like Figures 1 to 12As shown, a multi-point micro-force sensor 100 of the preferred embodiment is applied to an in-body muscle strength detection device 800, wherein the in-body muscle strength detection device 800 includes a shell 810, a processor 820 and one or more multi-point micro-force sensors 100, wherein the outer surface of the detection area of ​​the multi-point micro-force sensor 100 has an outer layer 830, wherein the processor 820 is installed inside the shell 810, wherein the surface of the shell 810 has an effective working area, wherein the multi-point micro-force sensor 100 is installed on the surface layer or the effective working area of ​​the surface of the shell 810, wherein the multi-point micro-force sensor 100 is electrically connected to the processor 820, wherein the outer layer 830 is coated on the surface of the shell 810 to improve human affinity and flexibility, which can be a protective layer 830 covering the multi-point micro-force sensor 100.

[0087] During operation, the in-body muscle force detection device 800 is placed in a human body cavity, taking the pelvic floor muscles in the pelvic floor cavity as an example, wherein the outer layer 830 can directly contact the inner wall of the human body cavity, wherein the pressure exerted by the human body muscles such as the above-mentioned muscle group movements is applied to the multi-point micro-force sensitive sensor 100 in the effective working area through the outer layer 830, wherein the multi-point micro-force sensitive sensor 100 converts the received pressure-related information into an electrical signal and transmits it to the processor 820, and then the processor 820 processes the electrical signal by wire or wirelessly and sends it to the user end such as a mobile phone, a computer or the cloud, thereby completing this operation. It should be understood that the effective working area refers to the pressure-bearing area on the surface of the shell 810 where the muscle tissue of the human body cavity directly or indirectly exerts pressure when the in-body muscle force detection device 800 is in operation, wherein the multi-point micro-force sensitive sensor 100 is just arranged in the effective working area to detect and obtain the pressure-related information generated by the muscle tissue, such as muscle micro-force or muscle position point force, pressure change value, frequency, area or size, etc. For example, when the in-body muscle strength detection device is in operation, it can be completely placed in the human body cavity, so that the entire surface of the in-body muscle strength detection device can be subjected to pressure, that is, the surface of the in-body muscle strength detection device can be the effective working area, or the local pressure-bearing surface of the in-body muscle strength detection device is defined as the effective working area. In this embodiment, the shell 810 of the in-body muscle strength detection device 800 is implemented as an ellipsoidal structure, that is, the effective working area on the surface of the shell 810 is approximately implemented as an ellipsoidal area. Of course, the shell 810 can also be a cubic structure, a triangular structure, a pipe structure or other irregular structures, and accordingly, the effective working area on the surface of the shell 810 is also implemented as a corresponding shape area, which is not limited here.

[0088] Furthermore, the in-body muscle strength detection device 800 further includes an action unit 840, wherein the action unit 840 is operably mounted on the housing 810, and the processor 820 controls the action unit 840 to perform one or a series of active or passive stimulation, massage, detection or exercise actions, etc., wherein the action applied by the action unit 840 can directly act on the inner wall of the human body cavity through the outer layer 830 to stimulate the muscle tissue of the human body cavity to produce one or a series of contraction actions or tension actions. The pressure formed by the contraction action of the muscle tissue of the human body cavity can directly act on the outer layer 830 of the in-body muscle strength detection device 800, and act on the multi-point micro-force sensitive sensor 100 in the effective working area through the outer layer 830, and then the multi-point micro-force sensitive sensor 100 can detect and obtain the pressure-related information generated by the muscle tissue of the human body cavity, so as to complete the result feedback of the physical therapy, rehabilitation or massage of this operation.

[0089] Preferably, the action unit 840 is implemented as a vibration device that can generate a certain vibration frequency, or can provide different vibration frequencies to actuate the housing 810 to vibrate at a corresponding frequency, so that the inner wall of the human body cavity can be directly stimulated by the vibration to generate a corresponding contraction or tension action and feedback to the multi-point micro-force sensor 100. Alternatively, the action unit 840 is implemented as a bioelectric stimulation device, which stimulates the muscle tissue of the human body cavity through bioelectricity to cause the muscle tissue of the human body cavity to generate a corresponding contraction or tension action, so that the multi-point micro-force sensor 100 detects and obtains corresponding pressure-related information.

[0090] The outer layer 840 is preferably made of a medical health material such as a medical silicone material or other flexible material. At the same time, the outer layer 840 has a certain toughness, and will slightly deform or buffer when subjected to the pressure of the muscle tissue of the human body cavity, so as to protect the safety of human use and transfer the pressure to the multi-point micro-force sensitive sensor 100 in the effective working area inside. Alternatively, when in use, the user can apply some medical liquid, auxiliary lubricant or other human-friendly and safe auxiliary items or medicines that help stimulate the muscle tissue of the human body cavity, etc. on the surface of the outer layer 840 to help complete this operation.

[0091] It can be understood that the outer layer 840 can seal and wrap the shell 810 and the multi-point piezoelectric sensor 100 to prevent liquid from penetrating into the interior of the in-body muscle strength detection device 800 when the in-body muscle strength detection device 800 is cleaned, disinfected or soaked in disinfectant, so as to ensure that the internal components will not be damaged, etc., or affect the multi-point micro-force sensitive sensor 100 to malfunction.

[0092] like Figures 1 to 4 The multi-point micro-force sensitive sensor 100 of the present preferred embodiment includes a group of sub-detection components 10 and an output unit 20, wherein the sub-detection components 10 are installed on the surface of the shell 810 of the in-body muscle strength detection device 800, wherein each of the sub-detection components 10 is composed of at least one micro-force sensitive detection unit 11, wherein the micro-force sensitive detection unit 11 of the sub-detection component 10 is electrically connected to the output unit 20 for detecting multi-point pressure-related information in the effective working area of ​​the in-body muscle strength detection device 800 and the output unit 20 outputs an electrical signal to the processor 820 of the in-body muscle strength detection device 800.

[0093] Furthermore, each of the sub-detection components 10 forms a sub-detection area 110, and at least one of the micro-force-sensitive detection units 11 is arranged in each sub-detection area 110, wherein each of the micro-force-sensitive detection units 11 has a detection area 111, that is, the sub-detection area 110 is composed of at least one of the detection areas 111, wherein the detection area 110 is arranged in the effective working area of ​​the shell 810 of the in-body muscle strength detection device 800, wherein the outer layer 830 preferably covers the detection area 110, so that the outer layer 830 provides buffering protection for the micro-force-sensitive detection unit 11.

[0094] In the present invention, the group of sub-detection components 10 can be implemented as at least two sub-detection components 10, wherein the sub-detection components 10 are electrically connected to the output unit 20 respectively. Preferably, each sub-detection component 10 is electrically connected to the output unit 20 in series, or each sub-detection component 10 is electrically connected to the output unit 20 in parallel, or some of the sub-detection components 10 are electrically connected to the output unit 20 in series and some of the sub-detection components 10 are electrically connected to the output unit 20 in parallel, which can be realized in the algorithm data chain and is not limited here.

[0095] Further, each of the sub-detection components 10 includes at least one micro-force-sensitive detection unit 11, wherein the micro-force-sensitive detection units 11 of each sub-detection component 10 are preferably connected in series with each other, wherein the micro-force-sensitive detection units 11 of adjacent sub-detection components 10 are connected in series with each other and connected to the output unit 20. It can be seen that when any of the micro-force-sensitive detection units 11 fails or is damaged or cannot be detected, the sub-detection component 10 still has other micro-force-sensitive detection units 11 to continue working, thereby ensuring that the sub-detection area 110 will not lose data and destroy the integrity of the algorithm data chain of the multi-point micro-force-sensitive sensor 100, and ensuring the safety and reliability of the detection data.

[0096] Preferably, the output unit 20 is implemented as a piezoelectric conversion circuit, which can convert the pressure-related information received from the micro-force sensitive detection unit 11 into a circuit and transmit it to the processor 820. According to different circuit layout schemes, the output unit 20 can transmit two, three or more electrical signals to the processor 820, so that the processor 820 can use a differential grading algorithm to calculate multiple circuit signals to complete the differentiated comparison of multiple electrical signals and improve the detection accuracy.

[0097] Those familiar with the art should understand that the total pressure-related information obtained by the total detection area of ​​the multi-point micro-force-sensitive sensor 100, the pressure-related information obtained by the sub-detection area 110 of each sub-detection component 10, and the pressure-related information obtained by the detection area 111 of each micro-force-sensitive detection unit 11 can be output by the output unit 20 as three-way electrical signals and transmitted to the processor 820, and the processor 820 uses a differential grading algorithm to analyze and calculate the three-way circuit values ​​obtained by the detection to improve data accuracy. Of course, according to the layout of the circuit ground and the layout of the different positions of the sub-detection component 10 and the micro-force-sensitive detection unit 11, the processor 820 can use two-way, four-way, five-way or more types of circuit algorithms to obtain more accurate detection values ​​using a differential grading algorithm.

[0098] In this embodiment, after the micro-force-sensitive detection unit 11 collects the muscle micro-force of multiple points of the pelvic floor muscle, that is, the pressure-related information, the processor 820 calculates the size of the muscle micro-force of one or more points in the human body cavity detected by one or more micro-force-sensitive detection units 11 through an amplifying circuit or using MCU processing, and then determines the pressure-related information of the muscles at these points of the pelvic floor muscle, improves the sensitivity of obtaining the muscle micro-force, so that even a very small force can be converted and amplified into a certain electrical signal, so that the pressure-related information can be fed back as the vibration intensity of one or more vibration motors corresponding to the above-mentioned multiple points, or the intensity of the flashing of one or more lights, or presented as graphic changes of one or more images on a user end, etc., to enhance the user experience, or visualize the detection results so that the user or doctor can see them intuitively, which is convenient for the next exercise or rehabilitation adjustment.

[0099] Taking the pelvic floor muscle as an example, the in-body muscle force detection device 800 is placed in the pelvic floor cavity of the human body and directly or indirectly contacts the pelvic floor muscle, wherein one or more of the micro-force sensitive detection units 11 of the multi-point micro-force sensitive sensor 100 can detect the pressure-related information at one or more point positions of the pelvic floor muscle, and the output unit 20 is fed back to the processor 820, wherein the processor 820 feeds back the one or more pressure-related information to the user end, and presents one or more corresponding graphic changes of the images at the user end. In other words, according to the one or more pressure-related information of one or more points of the pelvic floor muscle detected and fed back by one or more of the micro-force sensitive detection units 11, the processor 820 feeds back the pressure-related information as one or more graphic changes of the images, and presents it on the display interface of the user end, such as a mobile phone screen or a computer screen, wirelessly or wired. That is to say, according to the different positions or sizes of each pressure-related information, the image is also displayed as different graphic changes, such as a coordinate graph, or an area graph, or a space graph, etc. People familiar with the art should understand that the image can intuitively display the pressure-related information corresponding to one or more points of the pelvic floor muscle, so that users can intuitively view the test results.

[0100] Therefore, this embodiment also provides a method for displaying a micro-force applied to the pelvic floor muscles, which comprises the following steps:

[0101] Obtaining information related to the pressure of muscles at one or more locations;

[0102] Calculate the size of the pressure related information by using an amplifying circuit or an MCU;

[0103] Graphic changes of one or more images corresponding to the pressure-related information are presented on a user terminal such as a mobile phone.

[0104] In another embodiment, based on one or more of the pressure-related information of one or more points of the pelvic floor muscles detected and fed back by one or more of the micro-force-sensitive detection units 11, the processor 820 feeds back the information to the action unit 840, and the action unit 840 applies one or a series of actions of corresponding intensity to these points of the pelvic floor muscles. Specifically, the action unit 840 is implemented as a vibration motor, wherein the vibration motor can apply corresponding vibration intensities to these points of the pelvic floor muscles, such as increasing, reducing or canceling the vibration intensity of certain points, etc., that is, one or more of the pressure-related information is fed back as the vibration intensity of one or more vibration motors corresponding to these points, so that these points of the pelvic floor muscles can be subjected to a predetermined vibration intensity, preventing some points of the pelvic floor muscles from having insufficient vibration intensity, or too high vibration intensity or no vibration intensity, etc., so as to optimize the exercise process.

[0105] In the above-mentioned method for displaying the micro-force applied to the pelvic floor muscles, step Z is replaced by step Z1, which feeds back the vibration intensity of one or more vibration motors corresponding to the pressure-related information.

[0106] In yet another embodiment, based on one or more of the pressure-related information of one or more points of the pelvic floor muscle detected and fed back by one or more of the micro-force-sensitive detection units 11, the processor 820 feeds back the pressure-related information to one or more lamps, and the lamps flash the corresponding light intensity brightness to intuitively present the magnitude of the pressure on these points of the pelvic floor muscle. For example, the lights corresponding to some muscle positions that are under greater pressure are brighter, and vice versa. Of course, it can also display different light colors corresponding to different pressure levels, which is not limited here.

[0107] In the above method for displaying the tiny force applied to the pelvic floor muscles, step Z is replaced by step Z2, which feeds back the intensity of the flashing of one or more lights corresponding to the pressure-related information.

[0108] It should be pointed out that the processor 820 may also be included in the multi-point micro-force sensitive sensor 100, that is, the micro-force sensitive sensor 100 has its own processing unit capable of processing the pressure-related information. In the present embodiment, the micro-force sensitive detection unit 11 located in the middle of each adjacent sub-detection component 10 is connected in series, so that each micro-force sensitive detection unit 11 of each sub-detection component 10 is connected in series, and the micro-force sensitive detection unit 11 at both ends is electrically connected to the output unit 20 to form a complete data transmission loop. Of course, the micro-force sensitive detection unit 11 of each adjacent sub-detection component 10 may also be two at the edge connected in series, or two locally connected in series, or two micro-force sensitive detection units 11 at any position connected in series, all of which should fall within the scope of protection of the present invention.

[0109] Preferably, the group of sub-detection components 10 are arranged in series transversely in the effective working area of ​​the shell 810, so that each sub-detection area 110 is arranged in parallel transversely around the surface of the shell 810, wherein the micro-force-sensitive detection unit 11 of each sub-detection component 10 is arranged in series longitudinally in the sub-detection area 110, so that the detection area 111 is arranged vertically in parallel in the sub-detection area 110, and then multiple detection areas 111 can detect pressure-related information at multiple points. In other words, each sub-detection area 110 is arranged transversely on the surface or surface layer of the in-body muscle strength detection device 800, wherein the micro-force-sensitive detection unit 11 is arranged longitudinally in the sub-detection area 110, so that more micro-force-sensitive detection units 11 can be arranged in the effective working area, and the detection area 111 of each micro-force-sensitive detection unit 11 will not overlap to affect the detection, so as to maximize the use of the effective working area. In addition, the sub-detection component 10 can also be arranged horizontally into two rows, or more rows, or the sub-detection component 10 can be arranged longitudinally in the effective working area, and the micro-force sensitive detection unit 11 can be arranged horizontally in the sub-detection area 110. Of course, the sub-detection component 10 and the micro-force sensitive detection unit 11 can also be arranged in the effective working area along other directions respectively, which is not limited here.

[0110] It should be pointed out that, according to the needs of the user, a certain number of the sub-detection components 10 are set in part of the effective working area, or a certain number of the micro-force sensitive detection units 11 are set in part of the sub-detection components 10, so as to arrange a certain size of the sub-detection area 110 in part of the effective working area or arrange a certain size of the detection area 111 in part of the sub-detection area 110, so as to detect the pressure-related information in the predetermined area. In other words, the sub-detection components 10 or the micro-force sensitive detection units 11 of different numbers or different positions and shapes can be arbitrarily arranged in the effective working area, and it can be understood by anyone familiar with the art that the changes or improvements in structure, quantity and position are all within the protection scope of the present invention.

[0111] For example, the group of sub-detection components 10 is set to four sub-detection components, and are numbered sequentially as the first sub-detection component 101, the second sub-detection component 102, the third sub-detection component 103, and the fourth sub-detection component 104, wherein the first sub-detection component 101 is composed of one micro-force sensitive detection unit 11A, wherein the second sub-detection component 102 is composed of two micro-force sensitive detection units 11B connected in series, wherein the third sub-detection component 103 is composed of four micro-force sensitive detection units 11C connected in series, and wherein the fourth sub-detection component 104 is composed of four micro-force sensitive detection units 11D connected in series. Each of the sub-detection components 101, 102, 103, 104 is sequentially arranged transversely on the surface of the shell 810 and connected in series to the output unit 20, wherein the two micro-force-sensitive detection units 11B of the second sub-detection component 102 are longitudinally arranged on the surface of the shell 810, wherein the four micro-force-sensitive detection units 11C of the third sub-detection component 103 are longitudinally arranged on the surface of the shell 810, and the four micro-force-sensitive detection units 11D of the fourth sub-detection component 104 are longitudinally arranged on the surface of the shell 810. In other words, the micro-force-sensitive detection units 11A, 11B, 11C and 11D are all arranged transversely on the surface of the shell 810 in parallel with each other, wherein each of the micro-force-sensitive detection units 11 forms a plurality of detection areas 111 arranged vertically and horizontally in the effective working area on the surface of the shell 810, so as to detect the pressure-related information at the corresponding positions on the surface of the shell 810 respectively.

[0112] like Figures 6 to 9 As shown, in this embodiment, the micro-force sensitive detection unit 11 includes a detection element 112 and a support member 113, wherein the support member 113 is installed on the surface or surface layer of the housing 810 and supports the outer layer 830, wherein the support member 113 forms a buffer cavity 114, wherein the surface of the detection element 112 forms the detection area 111, wherein the detection element 112 is operably fixedly installed at the bottom of the buffer cavity 114, so that the detection area 111 faces the outer layer 830, so that the buffer cavity 113 forms a buffer space that can buffer the pressure transmitted from the outer layer 830 to the detection element 112, protect the detection element 112 from damage or sensitivity reduction, etc., and extend the service life. The detection elements 112 of each micro-force sensitive detection unit 11 are connected in series and electrically connected to the output unit 20, so that the output unit 20 can receive pressure-related information at each position point.

[0113] During operation, the outer layer 830 is deformed toward the buffer cavity 114 due to external pressure, wherein the outer layer 830 transfers the pressure to the detection element 112 at the bottom of the buffer cavity 114 after deformation, so that the outer layer 830 needs to pass through the buffer of the buffer cavity 114 after being compressed before transferring the external pressure to the detection element 112, thereby protecting the detection element 112 from being directly affected by a large external pressure to prevent damage, etc.

[0114] The detection element 112 is implemented as a piezoelectric film material, such as AIN, ZNO, PZT or PVDF piezoelectric film, which has a low piezoelectric coefficient and can sensitively convert the pressure on the surface into pressure-related information such as circuit parameters, and transmit it to the output unit 20, thereby converting the pressure-related information into a current signal to complete the operation.

[0115] Preferably, if Figure 5 As shown, the detection element 112 includes a tray 1121 and a pressure element 1122, wherein the pressure element 1122 is capable of converting a pressure signal into an electrical signal, wherein the pressure element 1122 forms the detection area 111 in the middle of the tray 1121, wherein the pressure elements 1122 of the detection element 112 of each micro-force sensitive detection unit 11 are connected in series to transmit the electrical signal to the output unit 20. The tray 1121 is mounted and fixed to the bottom of the buffer cavity 114 of the support frame 113, wherein the trays 1121 of each detection element 112 of the same sub-detection assembly 10 are integrally connected together and each pressure element 1122 is connected in series in the same direction.

[0116] It can be seen that the multi-point micro-force sensor 100 itself supports and forms a stable and reliable working area, namely the buffer cavity 114, to ensure the safe operation of the pressure element 1122 of the detection element 112, so that the shell 810 of the in-body muscle strength detection device 800 is not needed to provide a stable and reliable working area, thereby reducing the installation space of the micro-force sensitive detection unit 11 of the multi-point micro-force sensor 100, which is conducive to installing a larger number of the micro-force sensitive detection units 11 in the effective working area and improving the detection sensitivity.

[0117] In this embodiment, the support member 113 is implemented as a plastic bracket with a certain hardness, wherein the surface of the housing 810 is provided with a plurality of corresponding mounting positions, wherein the support member 113 is detachably mounted at the mounting position of the housing 810. It is understandable that the support member 113 may be bonded to the mounting position on the surface of the housing 810 by solid glue or liquid glue, or may be integrally formed at the mounting position, or the support member 113 may be screwed, snap-fitted, or installed at the mounting position on the surface of the housing 810 by interference fit, and no limitation is made here, and it is only necessary to fix the support member 113 to ensure that the detection element 112 can work normally.

[0118] Preferably, the support member 113 is a slot-shaped bracket, in which a circular slot-shaped buffer cavity 114 is formed in the middle for accommodating and installing the detection element 112, wherein the detection element 112 can be bonded and fixed to the bottom of the buffer cavity 114 of the support member 113, and a buffer space is maintained with the protective member 830, so as to ensure the working safety of the detection element 112 without affecting its detection sensitivity. Of course, the support member 113 can also be a cylindrical structure, in which a circular hole-shaped buffer cavity 114 is formed in the middle, wherein the bottom of the buffer cavity 114 is arranged on the shell 810, and the detection element 112 is supported and fixed by the shell 810, wherein the support member 113 can be integrally formed on the surface of the shell 810.

[0119] It is understandable that the side wall of the support member 113 can be inclined inward to form the buffer cavity 114 in the shape of a circular groove with a gradually increasing opening, that is, the inner wall of the support member 113 is configured to be an inclined surface or an arc surface or a basin-like bottom, wherein the detection element 112 is arranged at the central bottom of the buffer cavity 114 to provide a good use effect. Of course, the buffer cavity 114 can also be configured to be an arc groove, a square groove, etc., which is not limited here.

[0120] In this embodiment, the support members 113 of each adjacent micro-force sensitive detection unit 11 are integrally formed and connected together, so that each micro-force sensitive detection unit 11 can be compactly arranged together, reducing the distance between adjacent micro-force sensitive detection units 11, and thereby arranging a larger number of the micro-force sensitive detection units 11 in the effective working area of ​​the shell 810.

[0121] like Figure 4As shown, further, a connection hole 1131 is formed between each adjacent support member 113, wherein the adjacent micro-force sensitive detection units 11 are connected in series through the connection hole 1131, wherein the micro-force sensitive detection units 11 at both ends are connected to the output unit 20 to complete normal operation. In this embodiment, the connection hole 1131 is implemented as a groove formed by the side wall of the support member 113 and a hole formed by the shell 810 to facilitate the installation and connection of the adjacent detection elements 112. Alternatively, the connection hole 1131 is a hole or a blind hole such as a groove formed by the middle or upper part of the side wall of the support member 113, which can also realize the mutual connection of the adjacent detection elements 112.

[0122] It is understandable that one of the support members 113 of the adjacent sub-detection components 10 can also be integrally connected together, so that each sub-detection component 10 is integrally fixed to the surface of the housing 810 to enhance the overall working stability. Of course, the adjacent support members 113 can also be mutually bonded, clamped, locked or mutually supported and fixed to the surface of the housing 810, which is not limited here.

[0123] It should be noted that the support members 113 of each micro-force-sensitive detection unit 11 can also be fixed to the surface of the housing 810 separately from each other, that is, each support member 113 is independently fixed to the housing 810. Alternatively, some of the support members 113 are arranged together, for example, the support members 113 of each sub-detection component 10 are fixed together, and only two adjacent support members 113 of adjacent sub-detection components 10 are fixedly connected, so that all the sub-detection components 10 are fixedly installed on the surface of the housing 810.

[0124] It is worth mentioning that the support frame 113 can be implemented as a hard material with good thermal conductivity, which can not only provide support for the outer layer 830, but also effectively conduct the working temperature of the detection element 112, so that the detection element 112 can dissipate heat well to ensure working safety and extend service life. Alternatively, a heat dissipation element, such as a heat sink, is provided at the bottom or side of the detection element 112.

[0125] like Fig.10 As shown, this embodiment also provides a method for manufacturing the multi-point micro-force sensitive sensor 100, which includes the following steps:

[0126] A. The sub-detection component 10 is formed by at least one micro-force-sensitive detection unit 11;

[0127] B. The detection element 112 of each of the micro-force-sensitive detection units 11 is fixedly mounted on the buffer cavity 114 of the support member 113, wherein the support member is fixedly mounted on the housing 810 of the in-body muscle strength detection device 800; and

[0128] C. Electrically connect a group of the sub-detection components 10 to the output unit 20.

[0129] It can be understood that the order of steps A, B and C can be changed arbitrarily, that is, each step can be performed independently without any particular order.

[0130] like Figures 6 to 9 As shown, preferably, the multi-point micro-force sensitive sensor 100 also includes a plurality of protrusions 831, wherein the plurality of protrusions 831 are arranged on the inner wall of the outer layer 830, wherein the protrusions 831 respectively correspond to the buffer cavity 114 facing the micro-force sensitive detection unit 11, so that when the outer layer 830 is compressed and deformed toward the buffer cavity 114 during operation, the protrusion 831 can first contact the pressure element 1122 of the detection element 112 and transfer the pressure to the pressure element 1122 of the detection element 112, so that the pressure element 1122 of the detection element 112 converts the pressure into pressure-related information such as circuit parameters, and then the outer layer 830 can transfer the pressure to the detection element 112 by the protrusion 831 without excessive deformation, thereby improving the detection sensitivity, while protecting the detection element 112 from damage and extending the service life.

[0131] Furthermore, the shape of the detection element 112 of each micro-force-sensitive detection unit 11 is set to be circular, elliptical, quasi-circular, square or other shaped structures, which are arranged exactly at the bottom of the buffer cavity 114, wherein the protrusion 831 corresponds exactly to the middle of the buffer cavity 114 and has a spacing tolerance D from the detection element 112, so that the protrusion 831 can contact and transmit pressure to the middle of the detection element 112 without being hindered by the support member 113, or preventing the support member 113 from interfering with the protrusion 831 in accurately transmitting the pressure to the detection element 112, so that the detection accuracy of the detection element 112 is guaranteed.

[0132] Specifically, the distance tolerance D between the protrusion 831 and the detection element 112 is implemented as 0-0.5 cm, preferably 0.15 cm. In other words, the protrusion end of the protrusion 831 can contact the detection element 112, or it can be at a certain distance from the detection element 112 without contacting, thereby achieving accurate pressure transmission operation.

[0133] Correspondingly, the manufacturing method of the multi-point micro-force sensitive sensor 100 also includes a step D, wherein the protective member 830 having a plurality of protrusions 831 is supported on the upper side of the micro-force sensitive detection unit 11, wherein the protrusions 831 are respectively corresponding to the buffer cavity 114 of each of the micro-force sensitive detection units 11.

[0134] Accordingly, the protrusion 831 is configured as a hemispherical structure or a semi-elliptical structure to match and transmit pressure to the detection element 112 in the middle of the buffer cavity 114. Of course, the protrusion 831 can also be configured as a square, annular or other structure, or each buffer cavity 114 is provided with a plurality of protrusions 831.

[0135] It should be noted that the shape and size of the detection element 112 of each micro-force-sensitive detection unit 11 can be freely set, that is, they can be the same, different, or partially the same, so as to adjust the size of the detection area 111. Or the sizes of the micro-force-sensitive detection units 11 of the same sub-detection component 10 are consistent, and the sizes of the micro-force-sensitive detection units 11 of different sub-detection components 10 are inconsistent, so that the sub-sensing areas 110 of the sub-detection components 10 at different positions are inconsistent, while the size of the detection area 111 in the same sub-detection area 110 is consistent, so as to adapt to receiving pressures of different sizes or areas at different positions.

[0136] In actual operation, due to the different positions of the muscle tissue in the human body cavity or the different directions of the applied force, the pressure intensity or pressure area of ​​some positions on the surface of the in-body muscle strength detection device 800 is different. Therefore, according to the different surface force conditions of the in-body muscle strength detection device 800, the micro-force sensitive detection units 11 of corresponding number and size are arranged in the effective working area, so as to set the detection areas 111 of corresponding number and area in the local area of ​​the effective working area, so as to improve the detection accuracy of the multi-point film sensor 100.

[0137] For example, if some muscle tissues have a larger area and a correspondingly larger force application area, a larger number of smaller-sized micro-force-sensitive detection units 11 can be arranged in the area with a larger pressure area on the surface of the in-body muscle strength detection device 800, so that the force applied to the larger area can be finely divided and detected by more micro-force-sensitive detection units 11, and then the relevant information of the force applied by the larger muscle tissue can be analyzed from a larger number of data, so that the doctor or user can more accurately understand the training, massage or physical therapy feedback of the larger muscle tissue. Of course, the micro-force-sensitive detection units 11 of the multi-point micro-force-sensitive sensor 100 can also be implemented in other quantities and sizes to arrange different densities of the micro-force-sensitive detection units 11 in different working areas to meet the detection needs of the user, and there is no limitation here.
