A body-worn energy harvester

Abstract

The invention discloses a human body wearable energy harvester, which relates to the technical field of power generation devices and includes a thigh rod, a calf rod, a gear transmission speed-up mechanism, a pressure plate, a connecting assembly, a first connecting shaft and two symmetrically arranged on both sides of the thigh rod In the energy collection mechanism, the lower end of the thigh rod and the upper end of the calf rod form a rotational connection through the first connecting shaft, the gear transmission speed-up mechanism is arranged on the calf rod and is located between the thigh rod and the calf rod, and the gear transmission speed-up mechanism includes The power output shaft, the energy collection mechanism includes a coil box, a magnet box, a coil array, a magnet array and a one-way transmission assembly, and the power output shaft can drive the magnet box and the magnet array to rotate in one direction relative to the coil array and the coil box through the one-way transmission assembly . The body-worn energy harvester provided by the present invention is small in size, can be worn on the inner side of the knee joint to collect kinetic energy during human movement, has high output performance, and can be used to supply power to wearable electronic devices.

Description

technical field [0001] The invention relates to the technical field of power generation devices, in particular to a human body-worn energy harvester. Background technique [0002] In recent years, with the rapid development of wearable electronic devices such as smart bracelets, locators, and health monitors, as well as their wide application in medical, military, and Internet of Things fields, low-power wearable devices have increasingly become a part of people's daily life. an integral part of. With the rapid development of such wearable electronic devices, it also puts forward higher requirements for portable energy, such as longer service life and less pollution to the environment. In this regard, conventional electrochemical batteries are not suitable for powering wearable devices for a long time due to their limited lifetime and severe environmental pollution. Therefore, researchers at home and abroad have begun to turn their attention to sustainable green energy, su...
