[0002] Active implantable medical devices have been widely used in the detection and treatment of various diseases, such as pacemakers, defibrillators, and neurostimulators. Active implantable medical devices require an internal power source to continuously power their operation.

[0003] In related technologies, the power source for implantable medical devices can be either a disposable battery or a rechargeable battery. When a disposable battery is depleted, the patient needs to undergo surgery to replace it, which causes great pain and inconvenience. When a rechargeable battery is depleted, it can be wirelessly charged to recharge the battery inside the patient's body.

[0004] However, the charging process for rechargeable batteries in current implantable medical devices is painful for patients and very difficult. Summary of the Invention

[0006] To achieve the above objectives, a first aspect of this application provides a power generation device, which includes a power generation component and a drive component. The power generation component is configured to be disposed inside a living organism, and the drive component is configured to be located outside the living organism.

When the first magnetic element reciprocates relative to the power generation unit, the first magnetic element may come into contact with or separate from the first electrode plate, and the elastic element generates alternating pressure on the piezoelectric layer to form an alternating current between the first electrode plate and the second electrode plate.

[0015] As an optional implementation, the power generation unit may further include a second coil, and the housing may include an outer shell and an inner shell, with a cavity between the inner shell and the outer shell. The second coil is disposed in the cavity, wherein when the first magnetic element reciprocates relative to the power generation unit, the first magnetic element cuts the magnetic lines of force of the second coil, so that the second coil generates alternating current.

[0019] As an optional implementation, the driving component may further include a second detection unit configured to detect external environmental information of the driving component in order to start the driving unit based on the detected environmental information.

[0020] Secondly, this application also provides a battery system, which includes a battery and a power generation device as described above.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments 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. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] Implantable medical devices can be powered by either disposable or rechargeable batteries. Disposable batteries typically have a lifespan of 7 to 10 years. Once the battery is depleted, surgery is required to replace it, a process that poses safety risks and causes significant pain for the patient. Therefore, rechargeable batteries are now being used in medical devices. When the rechargeable battery is depleted, it can be recharged wirelessly or through the patient's own movement. However, wireless charging, due to its eddy current heating effect, can cause burns to human tissue during the charging process, affecting human health. Furthermore, due to limitations in their physical condition, patients are often not suitable for strenuous exercise, making recharging through their own movement difficult and inefficient.

[0040] This application provides a power generation device, a battery system, and an electronic device. A dynamic magnetic field is formed by a driving component installed outside the human body to drive a power generation component installed inside the human body, thereby charging the battery inside the human body. The charging process does not cause discomfort to the human body and improves the convenience and efficiency of charging.

[0041] The following description, in conjunction with the accompanying drawings, illustrates the power generation device, battery system, and electronic device of this application. It should be noted that the electronic device of this application can be an implantable medical device, including but not limited to pacemakers and defibrillators, implantable cardiac contractility modulators, implantable circulatory support devices, various neurostimulators (e.g., brain pacemakers, spinal cord stimulators, vagus nerve stimulators, sacral nerve stimulators, phrenic nerve stimulators, etc.), assistive hearing devices, drug pumps, electrocardiogram recorders, etc. Furthermore, it may also include brain-computer interfaces, implanted chips, and other human-computer interaction devices. This application does not specifically limit these aspects.

[0042] Figure 1 This is a first schematic diagram of a power generation device provided in an embodiment of this application. Figure 2 This is a schematic diagram of the power generation components in the power generation device provided in the embodiments of this application.

[0043] Please refer to Figure 1 and Figure 2 This application provides a power generation device, which includes a power generation component 100 and a drive component 200. The power generation component 100 can be disposed on an implantable electronic device, while the drive component 200 can drive the power generation component 100 to generate electricity in a non-contact manner. That is, the power generation component 100 is configured to be disposed inside a biological body, and the drive component 200 is configured to be located outside the biological body, so that the power generation component 100 can charge the battery 300 in the implantable electronic device.

[0044] The power generation component 100 includes a power generation unit 120 and a first magnetic element 110. The first magnetic element 110 is movably disposed on the power generation unit 120. When the first magnetic element 110 moves relative to the power generation unit 120, the first magnetic element 110 can serve as a triggering mechanism for the power generation unit 120, causing the power generation unit 120 to generate electricity. The driving component 200 generates a dynamic magnetic field, which drives the first magnetic element 110 to move relative to the power generation unit 120.

[0045] In some embodiments, the drive assembly 200 may include a drive unit 220 and a second magnetic element 210, the second magnetic element 210 being opposite to the first magnetic element 110. The drive unit 220 is configured to drive the second magnetic element 210 to move. The second magnetic element 210 can generate a magnetic field. When the drive unit 220 drives the second magnetic element 210 to move, the second magnetic element 210 can form a dynamic magnetic field. Under the influence of this dynamic magnetic field, the second magnetic element 210 can drive the first magnetic element 110 to move, so that the first magnetic element 110 drives the power generation unit 120 to generate electricity. The dynamic magnetic field refers to the magnetic field formed by the position change of the magnetic field of the second magnetic element 210.

[0046] It is understandable that the first magnetic component 110 also generates its own magnetic field. The dynamic magnetic field generated by the second magnetic component 210 when it is active interacts with the magnetic field of the first magnetic component 110, so that there is a magnetic force between the second magnetic component 210 and the first magnetic component 110. Taking the repulsive force as an example, when the second magnetic component 210 moves close to the first magnetic component 110, the first magnetic component 110 will move away from the second magnetic component 210 under the action of the repulsive force. Taking the attractive force as an example, when the second magnetic component 210 moves, the first magnetic component 110 will follow the first magnetic component 110 under the action of the attractive force.

[0047] It should be noted that when the power generation component 100 is placed in an implantable electronic device inside the body, the drive component 200 is placed outside the body. Taking the human body as an example, the power generation component 100 can drive the first magnetic component 110 to move relative to the power generation unit 120 through the movement of the human body, thereby enabling the power generation unit 120 to generate electrical energy. The drive component 200 assists the first magnetic component 110 to move outside the human body through a dynamic magnetic field. Thus, for users with limited mobility, the power generation component 100 can also realize the charging function. The dynamic magnetic field of the second magnetic component 210 can drive the first magnetic component 110 to avoid the thermal burn effect, ensure the comfort of the human body during the charging process, improve the convenience and efficiency of charging, and the magnetic field itself can also play a role in magnetotherapy, which is beneficial to improving human health.

[0048] Furthermore, the mode of movement of the first magnetic element 110 depends on the mode of movement of the second magnetic element 210, that is, the mode of generating a dynamic magnetic field. The second magnetic element 210 can perform one-dimensional linear motion, or two-dimensional planar motion, such as rotational motion, or three-dimensional combination motion. The motion of the second magnetic element 210 can be regular or irregular, and this application embodiment does not specifically limit it.

[0049] The specific interaction process between the first magnetic component 110 and the second magnetic component 210 will be explained in detail below.

[0050] Please continue to refer to Figure 1 and Figure 2 In one possible implementation, the magnetic field axis of the first magnetic element 110 can be parallel to the magnetic field axis of the second magnetic element 210. The magnetic fields of the first magnetic element 110 and the second magnetic element 210 interact with each other. When the second magnetic element 210 is active, the first magnetic element 110 can interact along a preset trajectory. For example, the first magnetic element 110 can move in a straight line or rotate.

[0051] It is understandable that when the generator component is placed on an implantable electronic device inside the human body, the position of the first magnetic component 110 relative to the human body and the achievable movement trajectory can be known. The second magnetic component 210 can be placed in different positions outside the human body according to the specific posture of the human body and the position of the generator component 100 in the human body, so as to effectively drive the first magnetic component 110. For example, the second magnetic component 210 can be placed in front of the human body, behind the human body, or on the side of the human body.

[0052] In some embodiments, the magnetic field strength of the first magnetic element 110 and the magnetic field strength of the second magnetic element 210 can both be 1000 Gauss to 3000 Gauss. The magnetic field strength of the second magnetic element 210 can be a preset value or can be adjusted according to user needs.

[0053] For example, the magnetic field strength of the first magnetic element 110 and the second magnetic element 210 can be values ​​including but not limited to 1000 Gauss, 1500 Gauss, 2000 Gauss, 2500 Gauss, 3000 Gauss, etc. Preferably, the magnetic field strength can be controlled within the range of 1000 Gauss to 2000 Gauss, so as to have a good magnetic therapy effect on the human body without causing harm to the human body.

[0054] Figure 3 This is a second schematic diagram of the power generation device provided in the embodiments of this application. Figure 4 This is a third schematic diagram of a power generation device provided in an embodiment of this application.

[0055] In the power generation device provided in this application embodiment, the activity mode and trajectory of the first magnetic element 110 depend on the activity mode and trajectory of the second magnetic element 210. The following description will take the linear motion and rotational motion of the second magnetic element 210 as examples.

[0056] First, the method by which the second magnetic component 210 moves in a straight line will be explained.

[0057] Please refer to Figure 1 and Figure 2 In one possible implementation, the drive assembly 200 may further include a first controller 230a, which is electrically connected to the drive unit 220. The first controller 230a is configured to control the drive unit 220 to drive the second magnetic element 210 to reciprocate along the magnetic field axis of the second magnetic element 210, that is, the second magnetic element 210 can reciprocate in a straight line.

[0058] It is understandable that the dynamic magnetic field formed by the second magnetic component 210 is a magnetic field that moves along a straight line. As the second magnetic component 210 moves, the effect of the magnetic field of the second magnetic component 210 on the first magnetic component 110 alternates between strengthening and weakening, thereby driving the first magnetic component 110 to move back and forth relative to the power generation unit 120.

[0059] In some embodiments, the first magnetic element 110 and the second magnetic element 210 may be arranged along the same straight line. The polarity of the end of the first magnetic element 110 facing the second magnetic element 210 is the same as the polarity of the end of the second magnetic element 210 facing the first magnetic element 110. Thus, when the second magnetic element 210 moves toward the first magnetic element 110, the repulsive force of the second magnetic element 210 on the first magnetic element 110 will cause the first magnetic element 110 to move away from the second magnetic element 210. When the second magnetic element 210 moves away from the first magnetic element 110, the force of the second magnetic element 210 on the first magnetic element 110 weakens, and the first magnetic element 110 can rebound, thereby performing reciprocating motion.

[0060] It should be noted that the dynamic magnetic field formed by the second magnetic component 210 can be either a permanent magnetic field or an electromagnetic field, and this application embodiment does not specifically limit it.

[0061] Please refer to Figure 1 and Figure 2 For example, the second magnetic element 210 can be a permanent magnet, so that the second magnetic element 210 can form a permanent magnetic field. As the driving unit 220 drives the second magnetic element 210 to move, the permanent magnetic field formed by the second magnetic element 210 also moves, thereby forming a dynamic magnetic field.

[0062] Please refer to Figure 1 and Figure 3For example, the second magnetic element 210 may include an iron core 211 and a first coil 212. The first coil 212 is wound around the iron core 211. The first controller 230a is electrically connected to the first coil 212 and supplies direct current to the first coil 212, so that the second magnetic element 210 can generate an electromagnetic field. When the current supplied to the first coil 212 is at a constant value, the intensity of the electromagnetic field formed by the second magnetic element 210 also remains constant. As the driving unit 220 drives the second magnetic element 210 to move, the electromagnetic field formed by the second magnetic element 210 also moves, thereby forming a dynamic magnetic field.

[0063] The following is a detailed description of the specific structure and method by which the first magnetic element 110 moves under the drive of the second magnetic element 210, thereby causing the power generation unit 120 to generate electricity.

[0064] Please refer to Figure 1 and Figure 4 In the power generation device provided in this application embodiment, the power generation unit 120 can use the movement of the first magnetic element 110 as a power source to promote power generation. The movement of the first magnetic element 110 relative to the power generation unit 120 can realize one or more power generation methods such as triboelectric power generation, piezoelectric power generation, or magnetic induction power generation, which will be described below.

[0065] In one possible implementation, the power generation unit 120 may include a housing 121 and a plurality of electrode plates 122. The first magnetic element 110 and the plurality of electrode plates 122 are both disposed inside the housing 121. The electrode plates 122 may include a metal layer 1222 and a first friction layer 1221. The outer wall of the first magnetic element 110 is provided with a second friction layer 111. The first friction layer 1221 and the second friction layer 111 are in contact.

[0066] It is understood that the electrode sheet 122 can be attached to the inner wall of the housing 121. When the first magnetic element 110 moves back and forth between different electrode sheets 122, the first friction layer 1221 and the second friction layer 111 generate charge through relative friction, causing the metal layer 1222 to generate electrostatic induction and polarization. Thus, when the second friction layer 111 rubs against the first friction layer 1221 of different electrode sheets 122 and moves back and forth, an alternating current is formed between the metal layers 1222 of the multiple electrode sheets 122.

[0067] For example, the first friction layer 1221 can be polyvinylidene fluoride (PVDF), the second friction layer 111 can be silicone rubber, and the metal layer 1222 can be aluminum or other conductive metals or alloys. In addition, multiple electrode plates 122 can be respectively disposed on both sides of the inner wall of the housing 121, with two electrode plates 122 disposed on each side. The second friction layer 111 can be disposed on both opposite sides of the first magnetic element 110, so that both sides of the first magnetic element 110 can move rubbed between the two electrode plates 122 to generate electrical energy.

[0068] In one possible implementation, the power generation unit 120 may include a housing 121, a first electrode plate 123, a second electrode plate 124, and an elastic member 126. The elastic member 126 may be connected between the first electrode plate 123 and the second electrode plate 124. The side of the second electrode plate 124 facing the first electrode plate 123 has a piezoelectric layer 1241.

[0069] It is understandable that when the first magnetic element 110 reciprocates relative to the power generation unit 120, the first magnetic element 110 can come into contact with or separate from the first electrode plate 123, and the elastic element 126 exerts alternating pressure on the piezoelectric layer 1241. When the piezoelectric layer 1241 is squeezed, the piezoelectric layer 1241 generates a piezoelectric potential. In order to balance this piezoelectric potential, electrons flow from the first electrode plate 123 to the second electrode plate 124, thereby generating a current. As the elastic element 126 drives the first electrode plate 123 to rebound, the piezoelectric layer 1241 recovers, and the piezoelectric potential weakens. In order to balance the potential difference, electrons flow from the second electrode plate 124 back to the first electrode plate 123, thereby forming an alternating current between the first electrode plate 123 and the second electrode plate 124.

[0070] For example, the elastic element 126 can be a spring, and the first electrode plate 123 and the second electrode plate 124 can both be made of conductive metal materials such as aluminum plates. In addition, the first electrode plate 123 and the second electrode plate 124 can be arranged in pairs. The first electrode plate 123 and the second electrode plate 124 can be arranged at both ends of the reciprocating movement of the first magnetic element 110, so that piezoelectric power generation can be performed at both ends of the movement stroke of the first magnetic element 110 during the movement of the first magnetic element 110, and the elastic force of the elastic element 126 can assist the reciprocating movement of the first magnetic element 110.

[0071] In one possible implementation, the power generation unit 120 may include a housing 121 and a second coil 125. The housing 121 may include an outer shell 1211 and an inner shell 1212, with a cavity between the inner shell 1212 and the outer shell 1211, and the second coil 125 is disposed in the cavity.

[0072] It is understandable that when the first magnetic element 110 reciprocates relative to the power generation unit 120, the first magnetic element 110 moves back and forth inside the housing 121, and the first magnetic element 110 can cut the magnetic lines of force of the second coil 125 so that the second coil 125 generates alternating current, thereby achieving the effect of an electromagnetic induction generator.

[0073] It should be noted that the power generation device provided in this application embodiment can adopt one or a combination of the above-mentioned methods of triboelectric power generation, piezoelectric power generation and magnetic induction power generation. This application embodiment does not make specific limitations on this.

[0074] The following is a detailed description of how the second magnetic component 210 drives the first magnetic component 110 to move through rotational motion.

[0075] In one possible implementation, the drive assembly 200 may further include a second controller 230b, which is electrically connected to the drive unit 220. The output terminal of the drive unit 220 is connected to the axis of the second magnetic element 210. The second controller 230b is configured to control the drive unit 220 to drive the second magnetic element 210 to rotate in a plane parallel to the first magnetic element 110.

[0076] It is understood that both the first magnetic element 110 and the second magnetic element 210 can be permanent magnets, and the driving unit 220 can be a rotary motor. When the driving unit 220 drives the second magnetic element 210 to rotate, the second magnetic element 210 can form a rotating magnetic field, thereby driving the first magnetic element 110 to rotate synchronously. The rotating first magnetic element 110 can cause the power generation unit 120 to generate electricity.

[0077] In some embodiments, the first end of the first magnetic element 110 may be oriented in the same direction as the first end of the second magnetic element 210 but with opposite polarities, and the second end of the first magnetic element 110 may be oriented in the same direction as the second end of the second magnetic element 210 but with opposite polarities, so that the second magnetic element 210 has an adsorption force on the first magnetic element 110, and the first magnetic element 110 can rotate synchronously with the first magnetic element 110.

[0078] It should be noted that the first magnetic component 110 can generate electrical energy in the power generation unit 120 in a manner similar to that described above during its rotational motion, which will not be elaborated here.

[0079] In one possible implementation, the drive component 200 may further include a first detection unit 240, which is configured to detect the strength of the magnetic field interaction between the first magnetic element 110 and the second magnetic element.

[0080] It is understood that the first detection unit 240 can be a magnetic sensor, and the drive assembly 200 can be equipped with an instrument panel. The instrument panel can be used to display the detection results of the magnetic sensor. When using the power generation device of this application, the user can adjust their body posture according to the instructions on the instrument panel to ensure good charging efficiency. In addition, the magnetic sensor can be turned on automatically or manually through the guidance function of the instrument panel; this embodiment does not specifically limit this.

[0081] For example, the magnetic sensor may include, but is not limited to, a compass, a magnetic field sensor, a proximity sensor, etc., which can be used to sense the orientation of the first magnetic element 110. This application does not specifically limit the specific type and working principle of the magnetic sensor.

[0082] In some embodiments, the driving component 200 may further include a second detection unit 250, which is configured to detect external environmental information of the driving component 200, so as to activate the driving unit 220 according to the detected environmental information, thereby causing the second magnetic element 210 to form a dynamic magnetic field.

[0083] It is understood that the second detection unit 250 can be an infrared sensor. The infrared sensor can detect whether the user is close to the drive component 200. When the user is close to the drive component 200, the drive unit 220 is automatically started, so that the user can directly use the drive unit 220 to drive the power generation component 100 to generate electrical energy to charge the implanted electronic device. When the user leaves the drive component 200, the drive unit 220 is automatically stopped to save power, thereby improving the convenience of user operation and improving the user experience.

[0084] Figure 5 This is a schematic diagram of a battery system provided in an embodiment of this application.

[0085] Please refer to Figure 5 This application also provides a battery system, which includes a battery 300 and a power generation device as described above. The power generation component 100 in the power generation device is electrically connected to the battery 300 and charges the battery 300 under the drive of the drive component 200 in the power generation device.

[0086] The battery system may further include a rectifier module 400, a battery management module 500, and an alarm module 600. The rectifier module 400 and the battery management module 500 are connected between the power generation component 100 and the battery 300. The rectifier module 400 is used to rectify the AC power generated by the power generation component 100, thereby outputting current and voltage suitable for charging the battery 300.
