Portable human body energy harvesting system

Abstract

The invention discloses a portable human body energy harvesting system which comprises a plurality of piezoelectric transducer modules, a rectifying module, an output module and a storage module, wherein the plurality of piezoelectric transducer modules are located at all movable parts of the human body and are sequentially connected with the rectifying module and the output module. The mechanical energy generated by the human body is converted to the electrical energy through the piezoelectric transducer modules and is rectified and transported to the storage module or the output module through the rectifying module; the storage module provides the output module with the stored energy, and the output module finally provides the energy transferred from the storage module and the piezoelectric transducer module to the load. The portable human body energy harvesting system is simple and compact in structure and high in energy harvesting efficiency.

Description

technical field [0001] The invention relates to an energy collection system, in particular to a portable human body energy collection system. Background technique [0002] With the advancement of technology and the development of social economy, digital products with large screens and high functions have poured into people's lives. These electronic products with increasingly powerful functions have brought about a sharp increase in power consumption while facilitating people's lives. However, The battery technology in terms of capacity has only increased by 6% per year, which requires people to frequently charge their portable electronic products, and at the same time makes it very inconvenient for outdoor workers to charge their portable electronic products. As a result, there is greater demand for technologies that can harvest energy at any time to power electronic products that are carried around. [0003] Existing technologies that use human body activities to generate ...
