Title:
MOTION ENERGY HARVESTING CIRCUIT AND PORTABLE ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/095228
Kind Code:
A1
Abstract:
A motion energy harvesting circuit (100) and a portable electronic device (1000), the circuit (100) comprising: a power generation module (10) for converting kinetic energy generated by human motion to electrical energy, and outputting direct current; a low-frequency motion energy harvesting module (20) for harvesting the direct current outputted by the power generation module (10) when a human is in a low-frequency motion state; a high-frequency motion energy harvesting module (30) for harvesting the direct current outputted by the power generation module (10) when the human is in a high-frequency motion state; an energy storage module (40) being respectively connected to the low-frequency motion energy harvesting module (20) and the high-frequency motion energy harvesting module (30), so as to be used for storing the electrical energy; a motion switching module (50) being respectively connected to the power generation module (10), the low-frequency motion energy harvesting module (20) and the high-frequency motion energy harvesting module (30), so as to be used for monitoring the motion states of the human, and controlling, according to the motion states of the human, the low-frequency motion energy harvesting module (20) and the high-frequency motion energy harvesting module (30) to operate in a switching manner such that the low-frequency motion energy harvesting module (20) and the high-frequency motion energy harvesting module (30) can alternatively charge the energy storage module (40). The circuit (100) can avoid a waste of the motion energy, improving the efficiency of harvesting of the motion energy.
