Embodiment 1

[0014] See figure 1 , the micro power supply used in the human body in this embodiment includes a rubber capsule 1, a rubber column 2, a stainless steel tube 3, a thin-film thermocouple 4, a micro-thermoelectric generator 5, a wireless transmitting device 6, a signal processing system 7, and a liquid with a high ultrasonic absorption coefficient 8 and electrode 9.

[0015] The rubber bag 1 is provided with an inner cavity, and the liquid 8 with high ultrasonic absorption coefficient fills the inner cavity of the rubber bag 1 . The rubber column 2 and the rubber capsule 1 are bonded together by a rubber adhesive, and the cylindrical stainless steel tube 3 is overlaid on the rubber column 2 . The thin-film thermocouple 4 includes a hot end, a cold end and a signal output end. The hot end of the thin-film thermocouple 4 passes through the rubber bag 1 and is immersed in the high ultrasonic absorption coefficient liquid 8, and its cold end is arranged in the rubber column 2, and ...

Abstract

The invention discloses micro-power supply used inside human body, which comprises a rubber capsule, a rubber column, a stainless steel tube, a film thermocouple, a thermoelectric micro-generator, a wireless launcher, a signal processing system and electrodes; wherein, the rubber column and the rubber capsule are bound together by rubber cement; the stainless steel tube is sleeved outside the rubber column; the inner chamber of the rubber capsule is full of ultrasonic absorption coefficient liquid; the hot end of the film thermocouple penetrates the rubber capsule to soak into the ultrasonic absorption coefficient liquid, while the cold end is arranged in the rubber column; the hot end of the thermoelectric micro-generator penetrates the rubber capsule to soak into the ultrasonic absorption coefficient liquid, while the cold end is positioned in the rubber column; the wireless launcher and the signal processing system are both encapsulated in the rubber column, and sending antenna of the wireless launcher is welded on the stainless steel tube. The micro-power supply of the invention has the advantages of small volume, simple structure, and low cost, and ultrasound is safe to human body.

Description

technical field [0001] The invention belongs to the field of biological micro-electromechanical devices, and in particular relates to a micro-power supply for human body. Background technique [0002] The micro-power supply for human body is the application of micro-electro-mechanical systems (MEMS) technology in the field of biomedicine, that is, the field of biological micro-electro-mechanical systems (BioMEMS). [0003] Micro-medical devices in the human body work in the body, and the ideal energy source is electricity to drive micro-devices such as ultrasonic motors, cameras, and wireless transmitters. However, the current capacity of micro-batteries is limited, and it is still unable to meet the energy consumption of micro-medical devices in the body. Powering medical devices with cables inside the body is obviously not ideal. There are also many insurmountable difficulties in supplying power to micro-medical devices working in the complex environment of the human bod...
