Technical Field
[0001] This application belongs to the field of electronic product technology, specifically relating to a wearable device. Background Technology
[0002] In recent years, Virtual Reality (VR) technology has developed rapidly. Most VR devices on the market consist of two parts: a head-mounted display and a controller / set. By embedding inertial sensors and force sensors in the controller / set, the user's real hand movements are simulated, helping the user to complete interactive operations in the virtual scene.
[0003] However, existing VR glove products have a limited number of pressure sensors, and the positions of the pressure sensors are relatively fixed. Based on the position of the pressure sensors, only simple simulations of human hand movements can be performed, which cannot meet different sampling needs. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0026] The following is combined with Figures 1 to 4 The wearable device described in the embodiments of this application can be one of the following: electronic glasses, electronic gloves, electronic watches, electronic bracelets, electronic necklaces, etc.
[0027] Taking an electronic glove as an example, the wearable device includes: a wearing part 100, a detection part 200, and a dielectric element 300. The wearing part 100 is directly worn on the human body. The wearing part 100 serves as the main body of the entire wearable device and is used to fix the entire structure. A first electrode 1000 is provided on one side of the wearing part 100 or in the wearing part 100.
[0028] Depending on user needs, the wearable unit 100 has at least two mounting positions for mounting the detection unit 200. The detection unit 200 is detachably connected to one of the mounting positions, meaning the detection unit 200 can be mounted on the wearable unit 100 via the mounting position. A second electrode 2000 is provided on one side of the detection unit 200 or within the detection unit 200. Alternatively, the detection unit 200 can be movably connected to one of the mounting positions and movably mounted on at least two mounting positions, allowing the detection unit 200 to be moved to select the desired detection location.
[0029] The dielectric element 300 is made of a dielectric material and is connected to either the first electrode 1000 or the second electrode 2000, or both the first electrode 1000 and the second electrode 2000. When the detection unit 200 is connected to either of the mounting positions, that is, when the detection unit 200 is connected to the wearable unit 100, the dielectric element 300 is located between the first electrode 1000 and the second electrode 2000. A portion of the first electrode 1000 is opposite to a portion of the second electrode 2000 through the dielectric element 300, forming a capacitive pressure sensor 400.
[0030] Specifically, one of the first electrode 1000 and the second electrode 2000 serves as the cathode, and the other serves as the anode. Since the charged particles of the dielectric material in the dielectric element 300 are tightly bound by the internal forces of atoms and molecules or the forces between molecules, the charge of these particles is bound charge. Under the influence of the electric field of the first electrode 1000 and the second electrode 2000, these charges in the dielectric element 300 can only move within a microscopic range, generating polarization. The wearable part 100, in conjunction with the detection part 200, forms a capacitive pressure sensor 400 between the two electrodes.
[0031] The capacitance value formula (1) for the capacitive pressure sensor 400 is as follows:
[0032]
[0033] Where C is the capacitance value, ε0 is the vacuum permittivity, and ε r is the relative permittivity of the elastic dielectric material, A is the overlapping area of the first electrode 1000 and the second electrode 2000, and d is the distance between the first electrode 1000 and the second electrode 2000.
[0034] When using this wearable device, since the wearable part 100 is worn directly on the human body, during human movement, the wearable part 100 acts on the detection part 200 through the dielectric element 300. Relative movement occurs between the wearable part 100 and the detection part 200, causing a change in the distance between the first electrode 1000 and the second electrode 2000 corresponding to the pressure sensor 400. This results in a change in the capacitance value C, which can be used to detect the magnitude of pressure. For example, the smaller the distance d between the first electrode 1000 and the second electrode 2000, the larger the capacitance value C; conversely, the larger the distance d, the smaller the capacitance value C. By converting the pressure value detected by the pressure sensor 400 into human body movements, the movement of the human body can be accurately simulated.
[0035] Since the wearable part 100 of this embodiment is provided with at least two mounting positions, the detection part 200 can be installed at the part that needs pressure detection. Since the pressure sensor 400 is formed by a part of the first electrode 1000 and a part of the second electrode 2000 through the dielectric element 300, the location where the pressure sensor is formed can be changed by changing the mounting position, thereby meeting different sampling requirements and greatly increasing the flexibility of the pressure sensor layout in the wearable device.
[0036] In embodiments of this application, the wearable device includes a wearable part 100, a detection part 200, and a dielectric element 300. The wearable part 100 is provided with a first electrode 1000, and the detection part 200 is provided with a second electrode 2000. The dielectric element 300 is connected to the first electrode 1000 and / or the second electrode 2000. The wearable part 100 is provided with at least two mounting positions for mounting the detection part 200. Thus, when the detection part 200 is connected to either mounting position, the dielectric element 300 is located between the first electrode 1000 and the second electrode 2000. The first electrode 1000 can form a capacitive pressure sensor 400 with the second electrode 2000 through the dielectric element 300, which greatly increases the flexibility of the layout of the pressure sensor 400 in the wearable device and meets different sampling requirements.
[0037] It should be noted that the wearable part 100 has at least two mounting positions. Correspondingly, the detection part 200 has at least two, and each detection part 200 can be detachably connected to any one of the mounting positions. Alternatively, the detection part 200 can also be movably connected to one of the mounting positions, and each detection part 200 can move between multiple mounting positions to select the desired setting location. Thus, when multiple detection parts 200 are simultaneously set in one mounting position, the second electrode 2000 on each detection part 200, together with the first electrode 1000 and the dielectric element 300, forms a pressure sensor 400. Multiple pressure sensors 400 are formed on the wearable device. Based on the different formation positions, the multiple pressure sensors 400 measure the pressure changes at different positions, meeting the requirement of a higher sampling rate.
[0038] During human movement, the wearable part 100 at the corresponding position acts on the corresponding detection part 200 through the dielectric element 300. Relative movement occurs between the wearable part 100 and the detection part 200 at the corresponding position, causing a change in the distance between the first electrode 1000 and the second electrode 2000 of the pressure sensor 400 at the corresponding position. This results in a change in the corresponding capacitance value C, which can be used to detect the magnitude of pressure. By combining the pressure values detected by different pressure sensors 400 and converting them into the human body's movements, the human body's movements can be simulated more accurately.
[0039] In one embodiment, such as Figures 1 to 4As shown, the first electrode 1000 extends along a first direction on the wearable part 100, and the second electrode 2000 extends along a second direction on the detection part 200.
[0040] In this configuration, one of the first electrode 1000 and the second electrode 2000 serves as the cathode, and the other serves as the anode. When the detection unit 200 is connected to either of these mounting positions, the dielectric element 300 is located between the first electrode 1000 and the second electrode 2000. Due to the different extending directions of the first electrode 1000 and the second electrode 2000, the first electrode 1000 forms a capacitive pressure sensor 400 at the intersection of the dielectric element 300 and the second electrode 2000.
[0041] Depending on the different positions of the detection unit 200, the position of the first electrode 1000 relative to the second electrode 2000 through the dielectric element 300 changes, forming a pressure sensor 400 for different parts. This greatly increases the flexibility of the layout of the pressure sensor 400 in the wearable device and meets different sampling requirements.
[0042] In this embodiment, the first electrode 1000 extends along the Y-axis on the wearable part 100, and the second electrode 2000 extends along the X-axis on the detection part 200, that is, the directions in which the first electrode 1000 and the second electrode 2000 extend are perpendicular to each other. When the detection part 200 is connected to any of the mounting positions, the dielectric element 300 is located between the first electrode 1000 and the second electrode 2000, and the intersection of the first electrode 1000 and the second electrode 2000 is perpendicular, forming a capacitive pressure sensor 400 in conjunction with the dielectric element 300.
[0043] like Figure 4 As shown, the wearable part 100 is provided with a first electrode 1000 arranged along the Y-axis direction, and the detection part 200 is provided with three second electrodes 2000 arranged along the X-axis direction. The three second electrodes 2000 on the three detection parts 200, together with the dielectric element 300, form three pressure sensors 400 on the same first electrode 1000.
[0044] In one example, such as Figures 1 to 6 As shown, the wearable part 100 includes a flexible circuit board 1001. The flexible circuit board 1001 (Flexible Printed Circuit, FPC) is a highly reliable and extremely flexible printed circuit board made with polyimide or polyester film as a substrate. It features high wiring density, light weight, thinness, and good bendability.
[0045] Depending on the wearing location, the flexible circuit board 1001 can be configured with wearing spaces for different positions on the human body. For example, when the wearable device is worn on the hand, the flexible circuit board 1001 extends along the shape of the hand and is configured with a wearing space for the hand. When the wearable device is worn on the foot, the flexible circuit board 1001 extends along the shape of the foot and is configured with a wearing space for the foot.
[0046] To sense corresponding actions, the flexible circuit board 1001 has at least two mounting positions, allowing the detection unit 200 to be detachably connected to the flexible circuit board 1001, or the detection unit 200 can be movably connected to one of the mounting positions. Each detection unit 200 can move between multiple mounting positions to select the desired location. The flexible circuit board 1001 also has a first electrode 1000. A portion of the first electrode 1000, through a dielectric element 300, forms a capacitive pressure sensor 400 relative to a portion of the second electrode 2000.
[0047] In this embodiment, as Figure 5 and Figure 6 As shown, the detection unit 200 includes a ring. The ring extends around the surface of the flexible circuit board 1001. When the flexible circuit board 1001 is configured to have a wearing space for wearing on a person's hand, the ring can be configured as a finger ring. When the flexible circuit board 1001 is configured to have a wearing space for wearing on a person's foot, the ring can be configured as a toe ring. The ring extends along the shape of the flexible circuit board 1001, is detachably connected to one of the mounting positions, and can correspond to multiple fingers or toes depending on the number of corresponding fingers or toes.
[0048] The inner ring of the buckle is provided with a second electrode 2000, and a dielectric element 300 is disposed on the second electrode 2000. Thus, when the buckle is connected to any of the mounting positions, that is, when the inner ring of the buckle is connected to the through flexible circuit board 1001, the dielectric element 300 is located between the first electrode 1000 and the second electrode 2000, and a portion of the first electrode 1000 and a portion of the second electrode 2000 are connected through the dielectric element 300 to form a capacitive pressure sensor 400.
[0049] During human movement, the flexible circuit board 1001 acts on the ring buckle through the dielectric element 300, causing relative movement between the flexible circuit board 1001 and the ring buckle. This results in a change in the distance between the first electrode 1000 and the second electrode 2000 of the pressure sensor 400, thereby causing a change in the capacitance value C, which can be used to detect the magnitude of pressure. By converting the pressure value detected by the pressure sensor 400 into the movement of the human body, the movement of the human body can be accurately simulated.
[0050] To accurately simulate human movements, the wearable device also includes a processing unit 500. The processing unit 500, which may be a chip, processes the acquired pressure value. The processing unit 500 is mounted on the flexible circuit board 1001 and is electrically connected to the first electrode 1000. When the detection unit 200 is connected to either mounting position, the second electrode 2000 is electrically connected to the processing unit 500. Thus, when the pressure sensor 400 is formed, the processing unit 500 can acquire the magnitude of the pressure value, accurately simulating human movements.
[0051] In one embodiment, the wearable part 100 is a hand-shaped kit (glove), and the flexible circuit board 1001 includes a first flexible circuit board 1002 and a second flexible circuit board 1003. The first flexible circuit board 1002 and the second flexible circuit board 1003 are mated together to form a wearing space.
[0052] In this embodiment, the first flexible circuit board 1002 corresponds to the back of the human hand, that is, the first flexible circuit board 1002 is disposed on the back of the human hand and extends along the shape of the back of the human hand. The first flexible circuit board 1002 includes: a plurality of first detection areas corresponding to the back of each finger, each first detection area corresponding to the back of one finger. The second flexible circuit board 1003 corresponds to the palm of the human hand, that is, the second flexible circuit board 1003 is disposed on the palm of the human hand and extends along the shape of the palm. The second flexible circuit board 1003 includes: a plurality of second detection areas corresponding to the front of each finger, each second detection area corresponding to the front of one finger. Each first detection area and each second detection area are provided with a mounting position and a first electrode 1000. Thus, the front and back of the human fingers are provided with first electrodes 1000, so that when they are connected in a ring at different mounting positions, pressure sensors 400 can be formed on the front or back of different fingers.
[0053] When a finger joint bends or touches an object, the pressure sensor 400 is compressed, causing a change in the distance between the first electrode 1000 and the second electrode 2000 of the pressure sensor 400. This results in a capacitance value C, which is used to detect the magnitude of the pressure. By converting the pressure value detected by the pressure sensor 400 into the bending angle of the joint, the bending state of each finger of a human hand can be accurately simulated.
[0054] Based on the above embodiments, in one embodiment, such as Figure 5 and Figure 6As shown, one of the wearable part 100 and the detection part 200 is provided with an interface 600, and the other of the wearable part 100 and the detection part 200 is provided with a connector 700 that matches the interface 600. That is, the wearable part 100 and the detection part 200 are connected in a plate-to-plate manner. When the detection part 200 is connected to either of the mounting positions, the second electrode 2000 is electrically connected to the first electrode 1000 through the connector 700 and the interface 600. Thus, one of the first electrode 1000 and the second electrode 2000 serves as a cathode, and the other of the first electrode 1000 and the second electrode 2000 serves as an anode.
[0055] In this embodiment, the wearable part 100 is provided with an interface 600, and the detection part 200 is provided with a connector 700. Since the wearable part 100 has multiple mounting positions, in order to generate a pressure sensor 400 at the corresponding position when the detection part 200 is connected to any mounting position, each mounting position is provided with an interface 600. When the detection part 200 is set at any mounting position, it can be connected to the interface 600 through the connector 700 to form a corresponding capacitive pressure sensor 400.
[0056] Similarly, when at least two detection units 200 are provided, each detection unit 200 can be detachably connected to any of the mounting positions. Alternatively, the detection units 200 can also be movably connected to one mounting position, and each detection unit 200 can move between multiple mounting positions to select the desired location. Thus, when multiple detection units 200 are simultaneously installed at one mounting position, each detection unit 200 is connected to a corresponding interface 600 via a connector 700, forming multiple pressure sensors 400 on the wearable device. Based on the different formation positions, the multiple pressure sensors 400 measure the pressure changes at different locations, meeting the requirement for a higher sampling rate.
[0057] Based on the above embodiments, in one embodiment, such as Figure 5 and Figure 6 As shown, the wearing part 100 and the detection part 200 can be connected by Velcro. Velcro is a connecting fabric consisting of two parts: a nylon hook and loop strap 800 and a nylon fleece 900 strap. With slight pressure, the nylon hook and loop strap 800 and the nylon fleece 900 combined can generate a large fastening force and tearing force.
[0058] Specifically, one of the mounting position of the wearable part 100 and the detection part 200 is provided with a nylon hook and loop strap 800, and the other of the mounting position of the wearable part 100 and the detection part 200 is provided with nylon fleece 900. When the detection part is located in either of the mounting positions, the detection part 200 is connected to the corresponding mounting position by the nylon hook and loop strap 800 and the nylon fleece 900.
[0059] In this embodiment, the mounting position on the wearable part 100 is provided with nylon fleece 900, and the detection part 200 is provided with nylon hooks and loops 800. When the nylon hooks and loops 800 on the detection part 200 press against the nylon fleece 900, the nylon fleece 900 completes the connection with the wearable part 100. To improve the connection strength, multiple nylon fleece 900s can be provided on the mounting position, and correspondingly, multiple nylon hooks and loops 800 can be provided on the detection part 200. By connecting multiple nylon fleece 900s and multiple nylon hooks and loops 800, the connection strength between the wearable part 100 and the detection part 200 is effectively improved.
[0060] Based on the above embodiments, in one embodiment, such as Figures 1 to 6 As shown, the dielectric element 300 is made of a dielectric material and includes an elastic dielectric unit, which can be silicone, rubber, etc. The elastic dielectric unit is connected to the first electrode 1000 or the second electrode 2000, or simultaneously disposed on the first electrode 1000 and the second electrode 2000. When the detection unit is connected to either of the mounting positions, the elastic dielectric unit is located between the first electrode 1000 and the second electrode 2000, and pre-pressed between the first electrode 1000 and the second electrode 2000.
[0061] During human movement, the wearable part 100 at the corresponding position acts on the corresponding detection part 200 through the elastic dielectric unit. The elastic dielectric unit deforms under compression, causing relative movement between the wearable part 100 and the detection part 200. This results in a change in the distance between the first electrode 1000 and the second electrode 2000 of the pressure sensor 400 at the corresponding position, thereby causing a change in the corresponding capacitance value C, which can be used to detect the magnitude of pressure. By combining the pressure values detected by different pressure sensors 400 and converting them into human body movements, the movement of the human body can be simulated more accurately.
[0062] In addition, the surface of the elastic dielectric cell can be made into protrusions of different shapes, such as pyramid, cylinder, hemisphere, etc., to meet the different elasticity requirements of users.
[0063] Based on the above embodiments, in one embodiment, such as Figure 7As shown, the wearable unit 100 has multiple first electrodes 1000 arranged side by side, and the detection unit 200 has multiple second electrodes 2000 arranged side by side. Each first electrode 1000 or each second electrode 2000 is connected to a dielectric element 300, or both the first electrode 1000 and the second electrode 2000 are connected to a dielectric element 300. When the detection unit 200 is connected to any of the mounting positions, the multiple first electrodes 1000 and the multiple second electrodes 2000 are opposite each other through corresponding dielectric elements 300 to form multiple pressure sensors 400. By combining the pressure values detected by the different pressure sensors 400 and converting them into human body movements, the movement of the human body can be further simulated more accurately.
[0064] The advantage of this design is that the number and location of the pressure sensors 400 can be freely designed. For example... Figure 7 As shown, the wearable part 100 has three first electrodes 1000 along the Y-axis and three second electrodes 2000 along the X-axis attached to each finger. Capacitive pressure sensors 400 can be set at the intersection of the first electrodes 1000 and the second electrodes 2000, and a maximum of nine pressure sensors 400 can be formed.
[0065] In practical applications, more Y-axis and X-axis circuit branches or electrodes can be designed according to requirements, generating more capacitive pressure sensors 400 at different positions on the hand to meet the sampling rate and modeling needs that better reflect real human hand movements. This embodiment greatly increases the number and layout flexibility of the pressure sensors 400. Theoretically, any number of pressure sensors 400 can be placed at any position on the finger to simulate the user's real hand movements and help the user complete interactive operations in virtual scenarios.
