Abstract

This paper presents the design, fabrication, and characterization of a self-powered energy harvesting system in intermittent working mode. The system consists of an electromagnetic energy harvesting device, a self-driven power management circuit (PMC) and an electronic load. The harvesting device with nonlinear magnetic-spring configuration converts vibration energy into electrical energy from low-frequency hand shaking of human being. The PMC is able to regulate, store the generated energy, and smart control the powering of the electronic load without any external voltage supply. The self-powered energy harvesting system is constructed especially for the circumstance that the power generation is insufficient to directly power-up the load. Future potential application could be self-powered microelectronics and wireless sensor nodes.
