Vibration and piezoelectric power generation technology: mechanisms and enhancement of functionality.
S10517
★How can we improve the power generation efficiency of various energy harvesting methods? ★Vibration power generation, piezoelectric vibration power generation: specific evaluation methods and power generation mechanisms!
**Lecture Summary** Environmental energy harvesting technology, which extracts electrical energy from ambient energy sources such as light, heat, and vibrations, is gaining attention. This lecture will provide an overview of environmental energy harvesting technology, with a particular focus on vibration-based power generation devices that convert vibrations into electrical power. It will also introduce research examples related to the generation mechanisms and control circuits of electromagnetic, piezoelectric, and electrostatic devices, as well as approaches to enhance their functionality.
