A flexible and strong-driven human body energy harvester

Abstract

The invention relates to a flexible and strong-drive human body energy harvester, which includes a composite power generation device, a rope and a fixed end of the human body. Piezoelectric buckling beam, the up-frequency gear is fixed on the bottom plate, the up-frequency gear is meshed with the end gear of the inner ratchet, and the number of teeth of the up-frequency gear is greater than the number of teeth of the end gear of the inner ratchet, and the return spring is installed between the up-frequency gear and the bottom plate Between them, the permanent magnet installation wheel rotates in one direction under the drive of the inner ratchet. The permanent magnet installation wheel is embedded with a number of permanent magnets along the circumference array. Both the inner ratchet and the permanent magnet installation wheel are installed on the top plate. The energy management circuit board and the induction coil Installed on the top plate, the energy management circuit board is electrically connected with the induction coil and the piezoelectric buckling beam; the invention can avoid damage to the human body due to long-term wear and friction of the mechanical structure, minimize the impact on the movement of the human body, and has relatively High driving force.

Description

[technical field] [0001] The invention relates to the technical field of energy collection, in particular to a soft and strong drive type human body energy collector. [Background technique] [0002] Microelectronic devices are widely used in many fields such as industry, military, aerospace, biomedicine, environmental monitoring, and consumer electronics. Currently, these devices are mainly powered by chemical batteries, which have a limited lifespan and are harmful to the environment. With the rapid development of technologies such as new materials, micro-nano manufacturing and integrated electronics, the energy consumption required by microelectronic devices has been significantly reduced. The human body produces a large amount of energy and dissipates it in the environment during its daily activities. Capture biomechanical energy from human body movement, replace traditional batteries or extend the life of traditional batteries, and power portable and wearable micro-ele...
