[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0037] The following is combined with Figures 1-4 The present invention describes an energy transmission device and an auxiliary device based on flexible fabric.

[0038] It should be noted that the energy transmission device and the auxiliary equipment based on flexible fabric designed in this invention can transmit signals from one area of ​​a target object to another, such as signal transmission within a biological body or signal interconnection between electronic devices.

[0039] Figure 1 This is one of the structural schematic diagrams of the energy transmission device provided by the present invention, such as... Figure 1 As shown, the energy transmission device 100 includes the following: a repeater mechanism 110, an energy transmitting unit 120, and an energy receiving unit 130.

[0040] The repeater mechanism 110 is located above the surface of the target object. The repeater mechanism 110 includes at least one energy transmission path, each energy transmission path includes at least two repeaters, and each repeater is fabricated based on dense conductive fibers.

[0041] In this embodiment, the target object can be a human body, an animal, or other entity that requires power.

[0042] In this embodiment, at least one repeater of the repeater mechanism 110 is located above the body surface of the target object, without contacting the body surface (such as skin), and is aligned with the ground electrode as much as possible to ensure effective signal transmission.

[0043] In this embodiment, multiple repeaters in the repeater mechanism 110 constitute different energy transmission paths. In each energy transmission path, the repeater is used to enhance the coupling effect between the transmitting and receiving ground electrodes, reduce path loss, thereby extending the signal transmission distance and improving the signal reception strength.

[0044] In this embodiment, the shape, area, and position of each repeater in the repeater mechanism 110 can be set according to user needs. For example, the shape of the repeater can be designed as circular or square, and the area of ​​the repeater can be determined according to the size of the ground electrode corresponding to the target receiving end or transmitting end below. In addition, the installation position of the repeater in the repeater mechanism 110 can be determined according to the user's wearing habits or according to the usage standards of conventional medical auxiliary equipment.

[0045] In this embodiment, different energy transmission paths can transmit electrical signals individually or simultaneously to different energy transmission groups (one energy receiver and one energy transmitter) for device communication or power supply. Furthermore, to avoid unnecessary energy loss, the repeaters corresponding to the energy transmission groups are adaptively switched on and off according to application requirements.

[0046] The energy transmitting unit 120 includes a transmitting signal electrode and a transmitting ground electrode. The transmitting signal electrode contacts the surface of the target object, and the transmitting ground electrode is located below the repeater at the starting point of the target energy transmission path. The target energy transmission path belongs to at least one energy transmission path.

[0047] In this embodiment, it is assumed that the target energy transmission path includes repeater 1 and repeater 2. Repeater 1 is located above the body surface projection area corresponding to the energy transmitting ground electrode of the smart bracelet, and repeater 2 is deployed above the corresponding body surface projection area of ​​the energy receiving ground electrode of the implantable device. In this target energy transmission path, repeater 1 is the starting repeater and repeater 2 is the ending repeater.

[0048] In this embodiment, the energy transmitting unit 120 can convert its stored electrical energy into AC power and transmit electrical signals through the target energy transmission path in the repeater mechanism 110. Specifically, the energy transmitting unit 120 converts electrical energy into a high-frequency AC signal suitable for transmission in the human body, and then forms an energy transmission loop through the energy transmitting electrode and the receiving electrode of the receiving device. Based on the high conductivity of human tissue and the enhancement effect of the repeater mechanism 110 on the reverse coupling effect, energy can be efficiently transmitted over long distances through a pair of electrodes, thereby providing a stable power supply for wearable or implantable devices worn by users.

[0049] The energy receiving unit 130 includes a receiving signal electrode and a receiving ground electrode; the receiving signal electrode contacts the surface of the target object, and the receiving ground electrode is located below the repeater at the end of the target energy transmission path; the transmitting signal electrode and the corresponding receiving signal electrode form a forward path through the surface of the target object; the transmitting ground electrode and the corresponding receiving ground electrode form a reverse path together through the capacitive coupling effect between themselves and the repeater mechanism 110.

[0050] In this embodiment, the energy receiving unit 130 optimizes the reception efficiency of the high-frequency AC signal emitted by the energy transmitting unit 120 by placing the receiving ground electrode below the repeater at the end of the target energy transmission path. The received high-frequency AC signal is converted into a stable DC signal through rectification, filtering and voltage regulation. The converted DC signal can provide the required power to the electronic device. Rectification is the process of converting AC signal into DC signal, filtering is the process of removing AC components from DC signal, and voltage regulation is the process of ensuring the stability of output voltage.

[0051] The present invention provides an energy transmission device that uses the high conductivity of the surface of the energy transmitting unit and the enhancement effect of the reverse coupling effect by the repeater mechanism to transmit the transmitted electrical signal to the energy receiving unit through the target energy transmission path. By introducing the repeater mechanism, it is beneficial to realize the miniaturization and integration of the device, and can enhance the reverse coupling effect, thereby improving the stability and efficiency of signal transmission, while realizing efficient energy conversion and power supply.

[0052] Optionally, the energy transmitting unit 120 includes at least one of a first smart wearable device and a first implantable device; the energy receiving unit 130 includes at least one of a second smart wearable device and a second implantable device.

[0053] In this embodiment, smart wearable devices include, but are not limited to, smartwatches, health monitors, etc.; implantable medical devices include, but are not limited to, pacemakers, neurostimulators, etc., which receive energy from external sources through energy receiving units 130 on or inside the body; portable sensors include, but are not limited to, environmental monitoring sensors, motion tracking sensors, etc., which have communication or charging / discharging functions.

[0054] In this embodiment, the external energy source can be an independent power source, or it can be a first smart wearable device or a second smart wearable device.

[0055] In this embodiment, the energy transmitting unit 120 and the energy receiving unit 130 include a set of energy transmission paths. For example, the energy transmitting unit 120 is a smart wearable device, and the energy receiving unit 130 is an implantable device. Specifically, in a power supply scenario, the smart wearable device continuously supplies power to the implantable device through an energy transmission path. In a communication scenario, the smart wearable device sends a communication signal and transmits the communication signal to the implantable device through a specified energy transmission path. The communication signal can be a control command used to control the working state of the implantable device.

[0056] In this embodiment, the energy transmitting unit 120 includes multiple energy transmission paths. For example, the energy transmitting unit 120 includes a smart wearable device 1, and the energy receiving unit 130 includes an implantable device 1 and a smart wearable device 2. The implantable and wearable devices include two sets of electrodes (each set of electrodes includes a signal receiving electrode and a signal receiving ground electrode). The smart wearable device 1 sends an electrical signal to the implantable device 1 through the energy transmission path 1, and the smart wearable device 1 sends an electrical signal to the smart wearable device 2 through the energy transmission path 2.

[0057] In some embodiments, in the mutual charging mode between two devices, when one device enters a low-battery state, its communication module will automatically send a charging request command to the other device; subsequently, the device with the highest battery level switches to the energy transmission mode to provide charging support for the low-battery device; in this technology, since the increase in the number of devices does not affect the receiving power of each device, it can also supply power to other devices while charging the low-battery device, thereby maximizing energy utilization without the need for additional energy transmission; in addition, users can replenish energy using a device that is easy to remove and has a large capacity (such as a mobile phone) with traditional charging technology (such as a charging cable), ensuring that the overall system has sufficient energy reserves.

[0058] The present invention provides an energy transmission device that communicates or supplies power to one or more energy receiving units through one or more energy transmitting units via different energy transmission paths, thereby improving the efficiency of communication and energy supply based on the human body as a transmission medium and the utilization rate of electrical energy.

[0059] Optionally, the multiple repeaters in the repeater mechanism 110 are arranged in a grid pattern; each repeater is connected by a fine conductive fiber, and the connection of each repeater follows the principle of the shortest distance.

[0060] In this embodiment, the repeaters are distributed in a grid pattern in the mechanism. Even if one repeater fails, the other repeaters can still maintain the network connection, which improves the redundancy and reliability of the energy transmission device 100 and helps to achieve full signal coverage and efficient transmission.

[0061] In this embodiment, since the fine conductive fiber is flexible enough to adapt to various complex layouts and installation environments, the repeaters in this embodiment are connected by the fine conductive fiber, which has the advantages of low signal loss and low electric field strength leakage when transmitting signals.

[0062] The present invention provides an energy transmission device by setting multiple repeaters in a grid-like distribution in a repeater mechanism. Each repeater is connected by a fine conductive fiber, and the connection follows the principle of the shortest distance. This can reduce material costs and installation complexity, reduce signal transmission delay and loss, and improve the redundancy and reliability of the energy transmission device.

[0063] Optionally, the area of ​​each repeater is larger than the area of ​​the transmitting ground electrode and the area of ​​the receiving ground electrode.

[0064] In this embodiment, by designing the area of ​​the repeater to be larger than the areas of the transmitting ground electrode and the receiving ground electrode, the equivalent parallel plate capacitor formed between the repeater and the corresponding ground electrode has a larger plate area, which helps to increase the capacitance effect, that is, to enhance the coupling capacitance between the ground electrodes of each device. Since the path loss is mainly determined by the coupling capacitance in the reverse path, the enhancement of the coupling capacitance can reduce the signal loss during transmission, thereby reducing the energy lost by the signal during transmission due to attenuation, scattering and other reasons (i.e., path loss during signal transmission).

[0065] In this embodiment, the position center of each repeater can be aligned with the position center of the device below to enhance the coupling capacitance between the ground electrodes of each device and reduce path loss.

[0066] The energy transmission device provided in this embodiment of the invention enhances the coupling capacitance between the ground electrodes of each device by designing the area of ​​the repeater to be larger than the area of ​​the transmitting ground electrode and the receiving ground electrode, thereby reducing the reverse path loss during signal transmission and further improving the energy transmission efficiency.

[0067] Optionally, the energy transmission device 100 also includes a controller 140.

[0068] The controller 140 is used to control the opening or closing of each energy transmission path according to the user's first instruction.

[0069] In this embodiment, the first instruction may be generated by the user through touch input, voice input, or key input.

[0070] In this embodiment, the controller 140 parses the received user input to determine the operation the user wishes to perform, such as turning on or off a specific energy transmission path, and generates a corresponding first instruction. Based on the parsed instruction, the controller 140 sends control signals to relevant components to regulate the energy transmission path, including but not limited to changing the state of switches, relays or other electronic components, thereby turning on or off a specific path.

[0071] In this embodiment, the controller 140 also has a real-time monitoring function, which can detect the status of the energy transmission path (such as whether it is conductive, the magnitude of the current, etc.). The controller 140 can also send feedback signals to the user based on the monitoring results, or automatically adjust the path status to ensure the stability and efficiency of energy transmission.

[0072] The present invention provides an energy transmission device that controls the conduction or cutoff of each energy transmission path according to the user's first instruction by a controller, thereby realizing rapid adjustment of the on / off state of each energy transmission path and improving energy transmission and regulation efficiency.

[0073] Optionally, the controller 140 is also used to control the signal transmission parameters of the energy transmission unit 120 according to a second instruction from the user.

[0074] In this embodiment, the second instruction is used to adjust parameters such as the signal transmission power, frequency, and waveform of the energy transmission unit 120; the controller 140 first parses the content of the second instruction and adjusts the signal transmission characteristics of the energy transmission unit 120.

[0075] In this embodiment, the frequency of the signal is adjusted by the second instruction to ensure that the signal is selected within the optimal transmission frequency band of the human body channel, thereby reducing signal attenuation and improving channel utilization. At the same time, the communication circuit architecture and data modulation method are optimized by the second instruction to achieve a low-power design of the system and reduce the energy consumption of the nodes. In addition, the application requirements of each node device can be fully considered by the second instruction, such as key performance indicators such as data transmission efficiency, energy utilization efficiency (energy efficiency ratio) and reliability.

[0076] In this embodiment, during the signal transmission parameter optimization process, a dynamic power management strategy can be further adopted to adaptively adjust communication parameters according to transmission requirements, thereby maximizing the system runtime while meeting performance requirements.

[0077] The present invention provides an energy transmission device that uses a controller to control the signal transmission parameters of an energy transmission unit according to a second instruction from a user, thereby enabling rapid adjustment of the signal transmission parameters of the energy transmission unit and improving the operational safety and energy utilization efficiency of the energy transmission device.

[0078] Optionally, the energy transmission device 100 also includes a power supply 150.

[0079] The power supply 150 is electrically connected to the energy transmitting unit 120 via a cable. The power supply 150 is used to provide a power signal. The energy transmitting unit 120 is also used to process the power signal by sequential signal conversion, modulation and filtering to obtain a high-frequency AC signal. The energy receiving unit 130 is also used to receive the high-frequency AC signal through the target energy transmission path, and to process the high-frequency AC signal by sequential rectification, filtering and voltage regulation to obtain a DC signal for powering the equipment.

[0080] In this embodiment, the power supply 150 can provide a power signal to provide overall power to the energy transmission unit.

[0081] In this embodiment, the power supply 150 can be a portable power supply 150 or a stationary power supply 150.

[0082] In this embodiment, the energy transmitting unit 120 converts the energy provided by the power supply 150 into AC power and outputs it to the transmitting signal electrode and the transmitting ground electrode. Specifically, the power supply 150 converts electrical energy into a high-frequency AC signal suitable for human transmission through the energy transmitting unit 120, and then forms an energy transmission loop through the energy transmitting electrode and the receiving electrode of the receiving device. Based on the high conductivity of human tissue and the enhancement effect of the repeater mechanism 110 on the reverse coupling effect, energy can be transmitted efficiently and over long distances through a pair of electrodes, thereby providing a stable power supply for wearable or implantable devices worn by users.

[0083] The present invention provides an energy transmission device that continuously provides a power signal to the energy transmission unit by setting a power source, thereby ensuring that the electrical equipment operates stably for a long time.

[0084] Optionally, the energy transmission unit 120 includes a loss compensation circuit 121.

[0085] The loss compensation circuit 121 is used to adjust the conjugate impedance matching of the energy transmission unit 120.

[0086] In this embodiment, since the capacitive impedance of the transmitting port is relatively large, it will cause signal reflection, thereby affecting the signal transmission efficiency and system performance. In this embodiment, a loss compensation circuit 121 is set in the energy transmitting unit 120 to adjust the conjugate impedance matching of the circuit. The loss compensation circuit 121 can compensate for these losses by introducing appropriate inductors, capacitors and other components, so that the impedance of the circuit reaches the conjugate matching state, thereby improving the signal transmission efficiency and system stability.

[0087] Specifically, the loss compensation circuit 121 in this embodiment compensates for the capacitive loss at the electrode port through conjugate matching. The loss compensation circuit 121 is composed of a few fixed inductors and array capacitors. The circuit monitors the transmitted or received voltage at the port in real time, or measures the port impedance, and completes the optimal adjustment of the capacitor parameters based on the closed-loop control strategy and the conjugate matching principle.

[0088] In this embodiment, for fixed devices such as permanently implanted devices, in order to reduce circuit power consumption, a one-time fixed compensation strategy can be implemented by manually measuring the port impedance.

[0089] The present invention provides an energy transmission device that improves the gain of the energy transmission device by setting a loss compensation circuit in the energy transmission unit to adjust the conjugate impedance matching of the energy transmission unit, and at the same time improves the communication energy efficiency ratio and energy transmission efficiency.

[0090] Optionally, the energy transmission unit is a HUB module, and the signal transmission frequency of the HUB module can be adjusted from 1MHz to 40MHz in 1MHz increments.

[0091] In this embodiment, the HUB module can transfer energy through conductive transmit signal electrodes and transmit ground electrodes.

[0092] In this embodiment, in the HUB power supply mode, the energy transmission unit is designed as a wearable HUB device. The HUB device is integrated into the human body channel network of flexible fabric and supplies power to other functional devices through the high-gain human body channel, thereby realizing the long-term operation of the energy transmission device.

[0093] In this embodiment, the signal transmission frequency of the HUB module should match the optimal transmission frequency band of the human body channel, and should be distinguished from the communication frequency to avoid interference and ensure efficient collaborative operation of the system in both communication and charging.

[0094] The present invention provides an energy transmission device, which uses a HUB module as the energy transmission unit and sets the signal transmission frequency of the HUB module to be adjustable from 1MHz to 40MHz, thereby further improving the gain of the energy transmission device and ensuring the long-term stable operation of the energy transmission device.

[0095] Figure 2 This is the second schematic diagram of the energy transmission device provided by the present invention. Figure 2In the illustrated embodiment, the human body local area network device mainly includes two types of devices: wearable and implantable. The energy transmitting unit can be either implantable device 1 or wearable device 1. For wearable device 1 (such as a smartwatch and health monitoring device), its signal electrode is attached to the back of the device, in contact with or close to the human body, while the ground electrode is on the front of the device, suspended in the air. For implantable device 1 (such as a brain pacemaker), its signal electrode and ground electrode are in direct contact with human tissue and are located on the farthest sides of the device. Similarly, the energy receiving unit can be either implantable device 2 or wearable device 2. The installation position and method of the corresponding ground electrode and signal electrode are similar to those of implantable device 1 or wearable device 1, and will not be described again in this embodiment.

[0096] The auxiliary device based on flexible fabric provided by the present invention will be described below. The auxiliary device based on flexible fabric described below can be referred to in correspondence with the energy transmission device described above.

[0097] Figure 3 This is one of the structural schematic diagrams of the auxiliary device based on flexible fabric provided by the present invention, such as... Figure 3 As shown, the auxiliary device based on flexible fabric includes: an energy transmission device 100 and a flexible fabric 310.

[0098] The energy transmission device includes the following: a repeater mechanism, an energy transmitting unit, and an energy receiving unit.

[0099] The repeater mechanism is located above the surface of the target object. The repeater mechanism includes at least one energy transmission path, each energy transmission path includes at least two repeaters, and each repeater is based on dense conductive fibers.

[0100] In this embodiment, the target object can be a human body, an animal, or other entity that requires power.

[0101] In this embodiment, at least one repeater of the repeater mechanism 110 is located above the body surface of the target object, without contacting the body surface (such as skin), and is aligned with the ground electrode as much as possible to ensure effective signal transmission.

[0102] In this embodiment, multiple repeaters in the repeater mechanism 110 constitute different energy transmission paths. In each energy transmission path, the repeater is used to enhance the coupling effect between the transmitting and receiving ground electrodes, reduce path loss, thereby extending the signal transmission distance and improving the signal reception strength.

[0103] In this embodiment, the shape, area, and position of each repeater in the repeater mechanism can be set according to user needs. For example, the shape of the repeater can be designed as circular or square, and the area of ​​the repeater can be determined according to the size of the ground electrode corresponding to the target receiving end or transmitting end below. The installation position of the repeater in the repeater mechanism can be determined according to the user's wearing habits or according to the usage standards of conventional medical auxiliary equipment.

[0104] In this embodiment, different energy transmission paths can transmit electrical signals individually or simultaneously to different energy transmission groups (one energy receiver and one energy transmitter) to enable device communication or power supply.

[0105] The energy transmission unit includes a signal transmitting electrode and a ground transmitting electrode. The signal transmitting electrode contacts the surface of the target object, and the ground transmitting electrode is located below the repeater at the starting point of the target energy transmission path. The target energy transmission path belongs to the at least one energy transmission path.

[0106] In this embodiment, it is assumed that the target energy transmission path includes repeater 1 and repeater 2. Repeater 1 is located above the body surface projection area corresponding to the energy transmitting ground electrode of the smart bracelet, and repeater 2 is deployed above the corresponding body surface projection area of ​​the energy receiving ground electrode of the implantable device. In this target energy transmission path, repeater 1 is the starting repeater and repeater 2 is the ending repeater.

[0107] In this embodiment, the energy transmitting unit can convert its stored electrical energy into AC power and transmit electrical signals through the target energy transmission path in the repeater mechanism. Specifically, the energy transmitting unit converts electrical energy into a high-frequency AC signal suitable for transmission in the human body, and then forms an energy transmission loop through the energy transmitting electrode and the receiving electrode of the receiving device.

[0118] The repeater mechanism of the energy transmission device is mounted on a flexible fabric.

[0119] In this embodiment, the flexible fabric can be various types of clothing, blankets, quilts, etc.

[0120] In this embodiment, the position coordinates and area occupied by each repeater on the flexible fabric are determined based on the area of ​​each repeater and its position relative to the human body, combined with computer control technology. In the actual manufacturing process, the repeater can be realized by forming a grid-like conductive sheet composed of dense conductive fibers, and connected by fine conductive fibers.

[0121] In this embodiment, in the flexible fabric, apart from the repeater and connecting wires which are constructed with conductive fibers, the other parts of the fabric can be made of non-conductive materials or conductive fibers, but they should not be connected to the conductive fibers of the repeater.

[0122] The flexible fabric-based auxiliary device provided in this embodiment can be widely used in health monitoring, smart wearables, implantable medical devices and other fields. It provides continuous power supply and low-loss communication path for medical auxiliary devices, ensures real-time monitoring and efficient data interaction of the system, and gives the device the possibility of long-term wear.

[0123] Figure 4 This is the second structural schematic diagram of the auxiliary device based on flexible fabric provided by the present invention. Figure 4 In the embodiment shown, Figure 4 (a) shows an auxiliary device (including conductive fiber repeaters, conductive fiber lines and flexible fabric) worn on a humanoid mannequin, with the conductive fiber repeaters connected to each other by conductive fiber lines. Figure 4 (b) shows two disc-shaped conductive fiber repeaters connected by conductive fiber lines. One conductive fiber repeater is located above the corresponding body surface projection area of ​​the wearable device via a flexible fabric, and the other conductive fiber repeater is deployed above the corresponding body surface projection area of ​​the energy receiving ground electrode of the implantable device.

[0124] The flexible fabric-based assistive device provided in this invention utilizes the high conductivity of the body surface through the energy transmitting unit of the energy transmission device. Combined with the enhancement effect of the reverse coupling effect by the repeater mechanism set on the flexible fabric, the transmitted electrical signal is transmitted to the energy receiving unit through the target energy transmission path. The structure is simple and facilitates the miniaturization and integration of the device. Moreover, by integrating the repeater into the flexible fabric, it can be seamlessly applied to human life. Combined with the human body channel communication and power supply modules of each device, the overall human body local area network system can support low-power interconnection communication and high-efficiency wireless power supply, thereby improving the stability and efficiency of signal transmission of the flexible fabric-based assistive device and enhancing the scalability of medical assistive applications.
