Abstract

The invention belongs to the field of vibration power generation and new energy. The invention aims to provide a tumbler type human motion energy harvester. The device can realize high-efficiency energy recovery of human body movement in a complex dynamic environment of human body movement. According to the technical scheme, the tumbler type human body motion energy harvester is characterized by comprising an arc-shaped outer frame, a magnetically controllable tumbler body and an electromagnetic induction coil structure, wherein the magnetically controllable tumbler body is positioned in the outer frame in a swinging mode, and the electromagnetic induction coil structure is installed in the arc-shaped outer frame and matched with the swinging end of the magnetically controllable tumbler body.

Description

technical field [0001] The invention belongs to the field of vibration power generation and new energy, and in particular relates to a tumbler-type human motion energy harvester. It can convert the energy of human motion into electrical energy, which can be used to power portable electronic devices, wireless sensors and other low-power devices, especially to provide emergency power supply for important electronic components such as positioning sensors of field personnel, reduce the risk of people losing contact in the field, and improve the Search and rescue success rate. Background technique [0002] With the widespread use of wireless sensors for distribution around the world, providing suitable energy supply devices for these wireless sensors has become the focus of related research. At present, wireless sensors are mainly powered by batteries. Batteries have limited life and need to be replaced or recharged frequently. At the same time, waste batteries have pollution pr...
