Detailed ways

In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

The core of the present invention is to provide a micro power generation device based on blood vessel pulsation. A schematic structural diagram of a specific embodiment of the invention is shown in Figure 1, including a semiconductor slide 03, a super-slippery conductive sheet 021 and an energy-capturing connector;

The energy-capturing connector is connected to the super-slippery conductive sheet 021 and the energized blood vessel, and is used to utilize the pulsation of the energized blood vessel to cause the super-slippery conductive sheet 021 to relatively slide on the semiconductor slide 03;

The super-slippery conductive sheet 021 makes super-sliding contact with the semiconductor slide 03 and outputs an electrical signal.

At present, there is no collection device that can directly collect the energy of blood vessel wall vibration. The reason why the present invention can be realized is because the high output density of ultra-slippery Schottky power generation can achieve miniaturization. At the same time, the friction force is extremely low and can be used in weak blood vessels. A certain displacement is generated under disturbance to generate electricity; at the same time, the wear-free feature eliminates the need for replacement. And because blood vessels are spread throughout the human body, they can be installed at any location to provide power for implanted devices used throughout the human body.

The super-slippery conductive sheet 021 includes a conductive island cover 212 and a super-slippery sheet 211;

The first surface of the super-sliding sheet 211 is in super-sliding contact with the semiconductor slide 03 , and the conductive island cover 212 and the super-sliding sheet 211 form ohmic contact, as shown in FIG. 5 .

Wherein, the first surface is a surface in contact with the semiconductor slide 03. When the super-slippery conductive sheet 021 includes a conductive island cover 212 and a super-slippery sheet 211, the super-slippery conductive sheet 021 is in contact with the semiconductor slide 021. Schottky power generation is used between the slideways 03. Of course, sliding power generation can also be achieved between the super-slippery conductive sheet 021 and the semiconductor slideway 03 in other ways, and the present invention is not limited here.

As a preferred embodiment, the micro power generation device also includes a conductive assembly 022;

The micro power generation device includes a plurality of the ultra-slippery conductive sheets 021;

A plurality of the super-slippery conductive sheets 021 are connected in parallel through the conductive assembly 022 and slide relatively on the semiconductor slide 03 driven by the energy-trapping connector. Of course, the super-slippery conductive sheets 021 connected by the same conductive assembly 022 can slide relatively on the same semiconductor slide 03 or on different semiconductor slides 03 .

In other words, using the energy-capturing connection to push multiple parallel-connected super-slippery conductive sheets 021 at one time can double the current and meet greater power requirements.

Specifically, the super-slippery conductive sheet 021 is a conductor or semiconductor slider with a single crystal two-dimensional interface;

The single crystal two-dimensional interface includes at least one of a graphite interface, a graphene interface, a molybdenum disulfide interface, a tungsten diselenide interface, a tungsten disulfide interface and a black phosphorus interface. Of course, the single crystal two-dimensional interface is the contact surface between the super-slippery conductive sheet 021 and the semiconductor slide 03 .

Furthermore, the energy-trapping connection member includes an elastic transmission member 011;

The direction in which the elastic transmission member 011 receives the pulsating force of the blood vessel is perpendicular to the sliding direction of the super-slippery conductive sheet 021 on the semiconductor slide 03 .

Please refer to Figure 1. After receiving the vertical downward force when blood vessels pulsate, the minor arc in Figure 1 is transmitted to the super-slippery conductive sheet 021 through the arc-shaped elastic material, so that the super-sliding conductive sheet 021 is in the figure. Slide horizontally. Preferably, the elastic transmission member 011 is an elastic polymer. Of course, other materials can also be selected according to actual conditions.

The elastic transmission member 011 with an arc-shaped structure has a simple structure, good force transmission performance, is easy to manufacture and has low cost. Of course, other shapes of structures can also be used to transmit the pulsating force of blood vessels.

Furthermore, the energy-trapping connector includes a contact bottom bracket 012;

The contact bottom bracket 012 covers the outer wall of the empowered blood vessel, and other structures of the energy capturing connector transmit the pulsating force of the empowered blood vessel to the super-slippery conductive sheet 021 through the contact bottom bracket 012 superior.

Furthermore, the energy-capturing connector includes at least two contact bottom brackets 012. The two contact bottom brackets 012 wrap the energized blood vessels from opposite directions to ensure that the energy of blood vessel pulsation is fully absorbed and transformed.

The contact bottom bracket 012 is a structure in which the energy capturing connector is in direct contact with the empowered blood vessel. The contact bottom bracket 012 can fit the empowered blood vessel, increase the force-bearing area, and make the empowered blood vessel The pulsations are better conducted to the super-slippery conductive sheet 021. In addition, the contact base 012 can also function as a protective cover to prevent the sharp structures of other parts of the micro power generation device from stabbing blood vessels (as shown in the figure) The endpoint of the elastic transmission member 011 in 1), the energy capture connector is not directly identified in Figure 1, but the components of the energy capture connector, namely the contact bottom bracket 012 and the elastic transmission member are respectively identified Item 011.

In addition, the super-slippery conductive sheet 021 is a graphite sheet. Graphite is relatively stable in the human body environment and does not react chemically with other components in the body. It is relatively safe for the human body and has excellent electrical conductivity, reducing losses in micro power generation devices.

As a specific implementation, it also includes a pre-pressed frame 04;

The micro power generation device is fixedly connected to the energized blood vessel through the pre-pressure frame 04, and the pre-pressure frame 04 applies pre-pressure to the energized blood vessel through the energy capturing connection piece.

Apply slight pressure to the empowered blood vessel to make the energy-capturing connecting piece fit more closely with the empowered blood vessel, and a larger part of the pulsation of the empowering blood vessel is received and conducted to the energy-capturing connecting piece. on the super-slippery conductive sheet 021.

Furthermore, a pre-pressure air bag is provided in the pre-pressure frame 04, and the pre-pressure air bag exerts pre-pressure on the empowered blood vessels. Through the pre-pressed air bag, the fit between the pre-pressed frame 04 and the empowered blood vessel can be made closer, so that the pulsating energy of the empowered blood vessel can be better converted, and at the same time, the pre-pressed frame 04 can be The pressure balloon can further act as a sensor for blood pressure measurement.

It should be noted that the shape of the pre-pressed frame 04 is changeable, as shown in Figure 1. The pre-pressed frame 04 in Figure 1 is a gasket in a pre-compressed state and is not related to the energy capture. The contact side of the connector directly fits with other tissues of the human body, and through its own pre-compression state, relies on the support of other tissues of the human body to provide pre-pressure to the empowered blood vessels. Of course, the specific appearance and installation means of the preloaded frame 04 can be changed accordingly according to actual conditions.

We estimate the energy that blood vessels in various parts of the body can provide. Taking the brachial artery as an example, its outer diameter is 0.42-0.49cm, the pressure is about 100mmHg=13332Pa, the heart rate is 70, it only needs 1mm length, and the blood vessel changes by 10%, that is It has a power of 1mW. For other blood vessels, it can be installed from capillaries to aorta, and the power range is 50nW-6mW; while the friction of the structural ultra-slippery technology is almost 0, it can be considered to have almost 100% conversion efficiency, so this power It can also be considered as the output electrical power. This power is enough to drive many micro sensor devices, such as a new generation of brain-computer interface chips.

The micro power generation device based on blood vessel pulsation provided by the present invention includes a semiconductor slide 03, a super-slippery conductive sheet 021 and an energy-trapping connector; the energy-trapping connector is connected to the super-slippery conductive sheet 021 and the energized blood vessel. , used to utilize the pulsation of the empowered blood vessels to make the super-slippery conductive sheet 021 relatively slide on the semiconductor slide 03; the super-slippery conductive sheet 021 and the semiconductor slide 03 make super-sliding contact and output electric signal. The present invention is based on the principle that conductive ultra-smooth materials and flat semiconductor materials can generate electric current by sliding relative to each other (such as Schottky power generation). Through the energy-capturing connector, the mechanical energy during the contraction and relaxation of blood vessels is absorbed with high efficiency. It can be converted into electrical energy to power implanted micro devices or itself as a self-powered sensor. It can obtain a long-lasting and sustainable power supply method for implanted micro devices in the human body without causing any harm to the human body.

On the basis of the first embodiment, the energy-capturing connector is further improved to obtain the second embodiment. The structural diagram is shown in Figure 2, including a semiconductor slide 03, a super-slippery conductive sheet 021 and an energy-capturing connection. pieces;

The ultra-slippery conductive sheet 021 and the semiconductor slide 03 are in super-sliding contact and output electrical signals;

The energy capturing connector includes a movement group;

A single movement group includes two elastic transmission members 011; the elastic transmission member 011 is an arc-shaped structure, the arc tops of the two elastic transmission members 011 in the same movement group are opposite, and the two elastic transmission members 011 are arranged in an arc-shaped structure. The movement directions of the super-slippery conductive sheets 021 corresponding to the

pieces

011 and 011 respectively are opposite.

The difference between this embodiment and the above-mentioned embodiment is that multiple sets of elastic transmission members 011 with opposite arc tops are provided in this embodiment. The rest of the structures are the same as the above-mentioned embodiment and will not be described again.

In this specific embodiment, the energy-capturing connecting member includes a moving group composed of two elastic transmission members 011 with opposite arc tops. Each elastic transmission member 011 corresponds to one or a group of the super-slippery conductive sheets 021 (such as In Figure 2, each elastic transmission member 011 corresponds to a group of super-slippery conductive sheets 021) connected in parallel with the conductive assembly 022. When the empowered blood vessel pulsates, the two elastic transmission members 011 transmit in opposite directions. The force forms a mutually supporting "herringbone" structure, which improves the mechanical stability. At the same time, it increases the utilization efficiency of vascular pulsation and improves the power generation power. Of course, the energy capturing connection may include a single movement group or multiple movement groups.

On the basis of the second embodiment, the micro power generation device is further improved to obtain the second embodiment, whose structural schematic diagram is shown in Figure 3, including a semiconductor slide 03, a super-slippery conductive sheet 021 and an energy capturing connector. ;

The energy capturing connector includes a movement group;

pieces

011 and 011 are opposite;

The micro power generation device includes two semiconductor slides 03, and the two semiconductor slides 03 respectively correspond to the respective ultra-slippery conductive sheets 021 and the energy-capturing connectors;

The two semiconductor slides 03 are arranged opposite to each other.

The difference between this embodiment and the above-mentioned embodiment is that two semiconductor slides 03 are provided in this embodiment. The remaining structures are the same as those in the above-mentioned embodiment and will not be described again.

Please refer to Figure 3. Figure 3 shows two opposite semiconductor slideways 03 and matching energy capturing connectors and super-slippery conductive sheets 021. The semiconductor slideways 03 are provided on both sides of the energized blood vessel. It avoids that when the empowered blood vessel is set on one side, the empowered blood vessel will be subjected to unidirectional pressure from the side (from the energy capturing connector on one side) for a long time. The blood vessel that is subject to unilateral pressure for a long time is more fragile and more likely to rupture, and the use of this specific The structure of the double-sided semiconductor slide 03 in the embodiment balances the left and right lateral pressures of the empowered blood vessels, placing less burden on the blood vessels. At the same time, it can better capture the kinetic energy of the pulsation of the empowered blood vessels and improve power generation. efficiency.

When the micro power generation device includes the pre-pressed frame 04, the pre-pressed frame 04 is an elastic connecting belt;

Both ends of the elastic connection belt are connected to the two semiconductor slideways 03 respectively, and the elastic connection belt is a pre-stretched connection belt.

The elastic connection belt takes up little space, provides sufficient pre-pressure, and can also balance the relative positions of the two semiconductor slides 03, which is beneficial to the miniaturization of the device. Of course, other forms of pre-pressed frame 04 can also be used, and the present invention is not limited here.

The following is an example of actual power generation. Assume that the diameter D range of the blood vessel is (60nm (capillary), 4cm (ascending aorta)); the average blood pressure is 100mmHg = 13332Pa, and the average heart rate of a normal person is 70; the effective length of the ultra-micro generator is 1mm. Let the diameter of the blood vessel during relaxation be D1, the diameter during contraction be D2, the average blood pressure be P, and the heart rate be f.

Then the external work power of the vasoconstriction-diastitation of length L is:

W _{blood vessel to the outside} =P*L*(D1-D2)*f

Assuming that the change in blood vessel diameter is 10%, then:

W _{blood vessel to the outside} =P*L*10%*D1*f

The numerical value brought into the theoretical background can be obtained that the external power of the blood vessel W ranges from _{the external power of the blood vessel} to about 50nW-6mW.

In actual situations, since the energy provided by blood vessel pulsation is pulse type, it is assumed to be a sinusoidal signal, and the peak value is twice the root of the average value. The peak external power is 70nW-8.4mW. For example, when applied to the brachial artery (outer diameter is about 0.5cm), a power of 1mW can be obtained.

In addition, Figure 4 provides a schematic diagram of the connection circuit between the micro power generation device and electrical appliances (i.e., the implantable micro device, R in the figure). The semiconductor slide 03 and the super-slippery conductive sheet 021 They are the two poles of the power supply, and electrodes can be provided on the super-slippery conductive sheet 021 and the semiconductor slide 03 to facilitate circuit connection.
