Embodiment

[0019] An embodiment of the present invention provides an energy supply device for collecting movement energy of a living body, which can be applied to long-term energy supply for implantable medical electronic devices. Specifically, such as figure 1 As shown, it is a schematic structural diagram of an energy supply device for collecting energy from living organisms in an embodiment of the present invention, including an energy collection unit 101, a rectification unit 102, and an energy storage unit 103, wherein:

[0020] The energy collection unit 101 is configured to generate an induced current by sensing the potential difference between the living body and a reference ground when the living body where the energy supply device for collecting the moving energy of the living body is located moves;

[0021] The rectification unit 102 is configured to rectify the induced current output by the energy harvesting unit 101 into a direct current, and provide electric energy for the ...

Abstract

An energy supply device gathering organism motion energies and an interpolation medical electronic device comprise an energy gathering unit, a rectification unit and an energy storage unit; the energygathering unit is used for sensing the potential difference between the organism and a reference ground so as to form an induced-current when the organism moves; the rectification unit is used for rectifying the induced-current outputted by the energy gathering unit into a DC current, and providing electric energy for the energy storage unit and / or a load; the energy storage unit is used for storing the electric energy outputted by the rectification unit when the rectification unit outputs electric energy, and providing electric energy for the load when the rectification unit outputs no electric energy; the energy supply device can utilize friction electrification and an electrostatic induction principle to convert organism motion energy into electric energy, and rectifies and stores theelectric energy, thus providing a long term energy supply for the load, and reducing patient operation risks and economical burdens; in addition, the energy source is from the potential difference between the organism and the reference ground, thus forming a large induced-current, and providing a high output power.

Description

technical field [0001] The invention relates to the technical field of electric generators, in particular to an energy supply device for collecting the movement energy of living organisms. Background technique [0002] Implantable medical electronic devices, such as cardiac pacemakers and brain pacemakers, occupy an important position in the field of clinical medicine today, greatly improving patients' symptoms and quality of life, and have significant social and economic value . However, as an emerging development direction of medical devices, the development of implantable medical electronic devices still faces many problems to be solved, especially the problem of long-term energy supply. [0003] At present, implantable medical electronic devices mainly rely on batteries for power supply, and their working life is limited. Once the batteries are exhausted, patients have to face huge surgical risks and financial burdens again. In addition, some implantable medical electr...
