[0032] FIG. 1 is a diagram illustrating a biosignal collection system according to the present invention.

[0033] Referring to FIG. 1, the biosignal collection system (100) may include an implant chip device (110), a biosignal collection server (130), and a database (150).

[0034] The implant chip device (110) may correspond to an implantable bio-sensor driven by wireless power according to the present invention. The implant chip device (110) may be implemented by including an implantable substrate, and major components may be arranged and supported by the implantable substrate. In one embodiment, the implantable substrate may be implemented with a flexible material or a biocompatible material and may adaptively combine with changes in biological tissue while implanted in vivo.

[0035] Additionally, the implant chip device (110) can be implemented as a terminal device that can be attached to or implanted into the user's body. In one embodiment of the present invention, as shown in FIG. 1, it may be implemented as a single implant chip device (110), but it is understood that it may be implemented as a plurality of devices as needed. In this case, each implant chip device (110) may be attached to or implanted to different users, and multiple devices may be attached to or implanted to the same user simultaneously.

[0036] Additionally, the implant chip device (110) can be implemented as one device constituting the biosignal collection system (100) according to the present invention, and the biosignal collection system (100) can be implemented in various modified forms depending on the wireless power transmission method and the purpose of biosignal collection.

[0037] Additionally, the implant chip device (110) may be implemented to operate by being wirelessly connected to a biosignal collection server (130), and is not necessarily limited thereto, but may also be implemented by optionally including various types of sensors. In particular, the implant chip device (110) may be implemented by including at least one MCU (Micro Controller Unit) to perform independent operation.

[0038] Meanwhile, the implant chip device (110) can be connected to the biosignal collection server (130) via a near-field wireless network such as NFC (Near Field Communication) or BT (Bluetooth), and can operate independently without a separate power supply by receiving a wireless power signal. Therefore, when the implant chip device (110) is implemented in multiple numbers, each biosensor can perform 1:N multi-channel wireless communication with the biosignal collection server (130).

[0039] The biosignal collection server (130) may be implemented as a server corresponding to a computer or program that performs the operation of receiving biosignals collected from a user and analyzing them in conjunction with the implant chip device (110) according to the present invention. In addition, the biosignal collection server (130) may be connected to the implant chip device (110) via a wireless network and may transmit and receive data with the implant chip device (110) through the network. In addition, the biosignal collection server (130) may be implemented to operate in connection with an independent external system (not shown in FIG. 1).

[0040] In one embodiment, the biosignal collection server (130) may be implemented to include a wireless power transfer (WPT) module capable of wirelessly transmitting power to the implant chip device (110). In this case, the wireless power transfer module may be implemented to include an antenna to wirelessly transmit power. For example, the wireless power transfer module may include a loop antenna and may further include a reader connected to the loop antenna.

[0041] The database (150) may correspond to a storage device that stores various information required during the operation of the biosignal collection server (130). For example, the database (150) may store biosignal information collected from a user, or may store algorithms for biosignal analysis and information for wireless communication and power, but is not limited thereto, and may store information collected or processed in various forms during the process in which the biosignal collection server (130) supplies wireless power to the implant chip device (110) according to the present invention.

[0042] In addition, in FIG. 1, the database (150) is shown as a device independent of the biosignal collection server (130), but it is not necessarily limited to this and can be implemented as a logical storage device included in the biosignal collection server (130).

[0044] Figure 2 is a diagram illustrating the functional configuration of the implant chip device of Figure 1.

[0045] Referring to FIG. 2, the implant chip device (110) may include an in-body sensor (210), an in-body processor (230), an in-body memory (250), and a wireless power controller (270).

[0046] The in-body sensor (210) is placed on an implant substrate and can collect biosignals within the body. For example, the in-body sensor (210) may include a temperature sensor, a PPG (Photoplethysmogram) sensor, an ECG sensor, an ECOG sensor, etc. The temperature sensor is a sensor that measures the temperature of the body, the PPG sensor is a photoplethysmogram sensor that measures changes in blood flow within tissues, the ECG (Electrocardiogram) sensor is an electrocardiogram sensor that measures potential signals generated during the contraction and relaxation of heart muscles, and the ECOG (Electrocorticography) sensor is a sensor that measures electrical signals of the brain. The in-body sensor (210) may be fixedly placed in an in-body location suitable for measuring biosignals according to the characteristics of the data being measured and the type of sensor.

[0047] In one embodiment, the in vivo sensor (210) can be coupled to the implant substrate through a sensor socket including a physical connection terminal. That is, the sensor socket can be directly connected to the in vivo sensor while coupled to the implant substrate. At this time, the sensor socket may include a physical connection terminal that physically couples to the in vivo sensor. Additionally, the sensor socket may include a connection terminal implemented to enable universal connection regardless of the sensor type in order to be physically connected to various types of in vivo sensors (210). The placement location of the sensor socket on the implant substrate may be determined according to the shape or arrangement structure of the substrate.

[0048] The in-body processor (230) is placed on the implant substrate and can determine the wireless power transmission time and transmission period to be transmitted from the outside based on the type of biosignal. Here, the outside may correspond to a power transmission device that supplies wireless power and may be implemented by a biosignal collection server (130). The power transmission device may be implemented including an antenna and can transmit wireless power to the implant chip device (110) through the antenna. The in-body processor (230) can receive the biosignal measured by the in-body sensor (210) and store it in the in-body memory (250), and can determine the type of biosignal based on feature information extracted from the biosignal.

[0049] For example, heart rate, temperature, etc. may exhibit a pattern of change only within a specific range, while ECG, ECOG, PPG, etc. may exhibit an irregular pattern over time in fine measurement units. In this way, the in vivo processor (230) can extract the change pattern, periodicity, and frequency of occurrence of the biosignal as feature information and then determine the type of biosignal among various predefined types.

[0050] Additionally, the in vivo processor (230) can determine the wireless power transmission time and transmission period corresponding to the detected type of biosignal by using transmission time and transmission period information established in advance for each type of biosignal. Here, the transmission time may correspond to the time when the supply of wireless power from an external wireless power transmission device begins, and the transmission period may correspond to the time interval during which the supply of wireless power continues from the transmission time. Accordingly, the transmission of wireless power may be terminated when the transmission period has elapsed based on the transmission time. Meanwhile, the transmission time and transmission period information for each type of biosignal may be stored in a specific area of ​​the in vivo memory (250) and may be accessed restrictively by the in vivo processor (230).

[0051] In one embodiment, when periodicity of a biosignal is detected, the in vivo processor (230) can determine a wireless power transmission time and a transmission period corresponding to the periodicity. For example, the wireless power transmission time may correspond to the highest or lowest peak time of the periodic biosignal, and the wireless power transmission time may correspond to the interval between peaks. For example, if the biosignal is an ECG signal, the wireless power transmission time may correspond to the R-peak time, and the wireless power transmission period may correspond to the RR interval.

[0052] In one embodiment, the in-body processor (230) can generate a wireless power distribution schedule that matches the wireless power transmission time and transmission period, and activate a virtual communication path passing through at least an in-body sensor according to the reception of wireless power. Here, the wireless power distribution schedule may correspond to a power distribution plan for the operation of the implant chip device (110) while wireless power is supplied from the outside. That is, the in-body processor (230) can generate a virtual path as a communication path for delivering wireless power to each component, assuming that wireless power is normally received during the transmission period based on the wireless power transmission time. At this time, the virtual communication path may correspond to the wireless power transmission path.

[0053] Additionally, the in-body processor (230) may set up multiple communication paths independent of each other according to a wireless power distribution schedule, and in this case, the in-body processor (230) may selectively activate any one of the multiple communication paths. That is, wireless power distributed by the wireless power controller (270) may be transmitted along the currently activated communication path among the multiple communication paths, and the communication path may be set to pass through at least an in-body sensor so that an operation for collecting biosignals may be executed while wireless power is supplied from the outside.

[0054] In one embodiment, the in-body processor (230) can determine the priority of each component according to the operating state of the implant chip device (110) and generate a wireless power distribution schedule according to the priority. For example, the operating mode of the implant chip device (110) may include a biosignal collection mode, a transmission mode, etc. The biosignal collection mode may correspond to an operating mode that collects biosignals through the operation of an in-body sensor, and the transmission mode may correspond to an operating mode that transmits the collected biosignals via wireless communication. The in-body processor (230) may assign the highest priority to the in-body sensor according to the biosignal collection mode, and the wireless power distribution schedule may be generated such that the power transmitted to the in-body sensor has the highest proportion among the received wireless power. Additionally, the in-body processor (230) may assign the highest priority to the wireless power controller according to the transmission mode, and the wireless power distribution schedule may be generated such that the power for wireless power transmission has the highest proportion.

[0055] In one embodiment, the in-body processor (230) can calculate the transmission reliability regarding the transmission of wireless power from the outside based on transmission errors resulting from the reception of wireless power. That is, since the transmission of wireless power is significantly affected by various external environments, it is necessary to provide stable power transmission, and the in-body processor (230) can quantify the stability of transmission regarding biosignal measurement and collection through an evaluation of wireless power transmission from the outside. Accordingly, the transmission reliability may correspond to a numerical value of the extent to which wireless power transmitted from the outside is delivered to the implant chip device (110), and may be calculated based on the wireless power transmission time and transmission period determined through the in-body processor (230).

[0056] The in-body memory (250) is placed on an implant substrate and can store biosignals. To this end, the in-body memory (250) can be implemented as an internal memory of an MCU included in an implant chip device (110). Additionally, data stored in the in-body memory (250) can be accessed by an electrically connected in-body processor (230) and can be used in the biosignal collection process according to the present invention.

[0057] The wireless power controller (270) is placed on the implant substrate and can control the distribution of power required for processing biosignals by receiving wireless power based on the wireless power transmission time and transmission period. The wireless power controller (270) can execute an operation for receiving wireless power in conjunction with the in-body processor (230). That is, the wireless power controller (270) can perform the role of receiving wireless power from the outside and distributing wireless power to each internal component.

[0058] In one embodiment, the wireless power controller (270) can transmit wireless power through a communication path based on a wireless power distribution schedule when receiving wireless power. The wireless power controller (270) can transmit wireless power through an activated communication path according to the wireless power distribution schedule, and each component can perform independent operations using wireless power as a power source.

[0059] In one embodiment, the wireless power controller (270) detects a transmission error between the wireless power transmission time and transmission period and the actual transmission, and may request an update of the wireless power distribution schedule if the transmission error exceeds a preset threshold. In this case, the in-body processor (230) may update the wireless power distribution schedule in accordance with the request of the wireless power controller (270), and may reflect the transmission error during the update process. A larger transmission error may indicate that the wireless power transmission environment is poor, and the in-body processor (230) may update the wireless power distribution schedule for stable power distribution while minimizing power consumption.

[0060] In one embodiment, the wireless power controller (270) may transmit a first transmission error regarding the wireless power transmission time based on the start time of receiving wireless power and a second transmission error regarding the wireless power transmission period based on the end time of receiving wireless power, along with a schedule update request. Subsequently, the first and second transmission errors may be used to determine the transmission quality between the start and end of wireless power. The wireless power controller (270) may define and calculate the total error of the wireless power by applying different weights to each of the first and second transmission errors.

[0062] FIG. 3 is a flowchart illustrating the wireless power reception and distribution process performed on a wireless power driving-based implant chip according to the present invention.

[0063] Referring to FIG. 3, the implant chip device (130) can measure and collect biosignals within the body through an in-body sensor (210) (step S310). The implant chip device (130) can determine the type of biosignal through an in-body processor (230) (step S330), and can estimate the wireless power transmission time and transmission period, respectively, based on the type of biosignal (step S350). The implant measuring device (130) can receive wireless power through a wireless power controller (270) and can control the distribution of power required for processing biosignals according to the reception of wireless power (step S370).

[0065] FIG. 4 is a drawing illustrating an embodiment of an in-body sensor according to the present invention.

[0066] Referring to FIG. 4, the implant chip device (110) may be implemented as a biosignal chip comprising an in vivo sensor (210), an in vivo processor (230), an in vivo memory (250), and a wireless power controller (270). In this case, the biosignal chip may be implemented as a bioimplantable flexible material or a biocompatible material and may be protected by a bioimplantable platform protective coating. For example, the biocompatible material may be a material that does not cause a substantial inflammatory or immune response to biological tissue.

[0067] Specifically, the in-body sensor (210) can be connected to an implant substrate through a sensor socket that includes a physical connection terminal. At this time, the physical connection terminal can be implemented to be physically coupled with various in-body sensors (210). Additionally, the sensor socket can be implemented to include one or more sockets as needed, thereby providing an interface that can be expanded to multiple in-body sensors (210). For example, the sensor socket may include a serial interface or a general purpose input / output port (GPIO) as a physical connection terminal.

[0068] Additionally, the in-body sensor (210) can be implemented in various forms depending on the type and characteristics of the biosignal to be measured. For example, the in-body sensor (210) can be implemented by including two electrodes, a band-pass filter, an instrumentation amplifier, and an AD converter. As another example, the in-body sensor (210) can be implemented by including two electrodes, a differential amplifier, a high-pass filter, and a comparator, but is not necessarily limited thereto and can be implemented by selectively including various configurations.

[0069] The in-body processor (230) may be implemented as an MCU (e.g., CPU, etc.), but is not necessarily limited thereto. Accordingly, the in-body memory (250) may be implemented as the internal memory of the MCU. The wireless power controller (270) may be implemented to include an NFC interface and a regulator for wireless power and data communication.

[0071] FIG. 5 is a drawing illustrating an embodiment of an implant chip device including a loop antenna according to the present invention.

[0072] Referring to FIG. 5, the implant chip device (110) can be implemented to basically include an antenna formed on an implant substrate (510), and the implant substrate (510) can be protected together with the antenna through a bio-implantable platform protective coating.

[0073] In one embodiment, the implant chip device (110) may be implemented to include an implant substrate (510) and a loop antenna (530). The implant substrate (510) may be combined with the main components of the implant chip device (110) and may be implemented in a bioimplantable material. Additionally, while the implant substrate (510) is implanted and operates within the body, the loop antenna (530) may be implemented to be implanted within the body or to operate outside the body as needed. If exposed outside the body, the loop antenna (530) may be connected to the implant substrate (510) via a filament structure. Additionally, as the implant substrate (510) is protected by a bioimplantable platform protective coating, a portion of the loop antenna (530) may also be coated and protected.

[0074] In one embodiment, the loop antenna (530) may be implemented by including a single coil or a plurality of coils, and the plurality of coils may be implemented in a shape corresponding to the shape of the implant substrate. Figure (a) of FIG. 5 is an example implemented with a plurality of circular coils, and Figure (b) is an example implemented with a single square coil. The plurality of coils constituting the loop antenna (530) may also be formed spaced apart according to a predetermined interval and may be implemented with different materials.

[0075] Additionally, the loop antenna (530) may experience thermal deformation in each coil due to heat generated during the transmission and reception of power and data signals. At this time, differences in thermal deformation may occur depending on the material properties of each coil, and multiple coils may be arranged such that the degree of thermal deformation of the coil becomes greater as it moves away from the center of the coil. At this time, multiple coils may be implemented so that bending due to thermal deformation occurs in the same direction.

[0076] For example, if the loop antenna (530) is implemented to include three circular coils, each of the three circular coils may undergo bending with a radius of curvature due to thermal deformation. In this case, the thermal deformation of the outermost coil may be the greatest, and the thermal deformation of the innermost coil may be the smallest. Additionally, it may be preferable for the bending of each coil to be formed to have a radius of curvature between 5 and 25 mm with respect to the inner plane formed by the coil, and the difference in the radius of curvature between adjacent coils ( It may be desirable for the ) to be formed so as not to exceed a maximum of 10 mm.

[0077] In one embodiment, the loop antenna (530) may be implemented in the form of a patch that can be attached to biological tissue (e.g., skin). In this case, an insulation layer may be disposed between the loop antenna (530) and the skin tissue layer. Additionally, the insulation layer may be formed by including a plurality of layers made of different materials. In this case, the plurality of insulation layers may be implemented such that the permittivity of the insulator decreases as it moves away from the loop antenna (530). Additionally, some of the plurality of insulation layers may be implemented to divide the space between adjacent insulation layers into at least two independent spaces.

[0079] Although the present invention has been described above with reference to preferred embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as described in the following claims.
