Title:
MICRO POWER GENERATION APPARATUS BASED ON BLOOD VESSEL PULSATION, AND IMPLANTABLE MICRO DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/236532
Kind Code:
A1
Abstract:
A micro power generation apparatus based on blood vessel pulsation, and an implantable micro device. The micro power generation apparatus comprises a semiconductor runner, a super-lubricious conductive sheet and an energy harvesting connector, wherein the energy harvesting connector is connected to the super-lubricious conductive sheet and an energizing blood vessel, and is used for enabling the super-lubricious conductive sheet to slide relatively on the semiconductor runner by means of the pulsation of the energizing blood vessel; and the super-lubricious conductive sheet is in super-lubricious contact with the semiconductor runner, and outputs an electrical signal. By means of the present invention, on the basis of superlubricity-based Schottky power generation, i.e. the principle that a current can be generated by a conductive super-lubricious material sliding relative to a flat semiconductor material, an energy harvesting connector efficiently converts the mechanical energy during a contraction and relaxation process of a blood vessel into electric energy to supply the energy to an implantable micro device or to serve as a self-energized sensor itself, such that a sustainable implantable micro device power supply means having a relatively long service life in a human body can be obtained while the human body is basically not hurt.
