Over the last couple of decades, numerous piezoelectric footwear energy harvesters (PFEHs) have been reported in the literature. This paper reviews the principles, methods, and applications of PFEH technologies. First, the popular piezoelectric materials used and their properties for PEEHs are summarized. Then, the force interaction with the ground and dynamic energy distribution on the footprint as well as accelerations are analyzed and summarized to provide the baseline, constraints, potential, and limitations for PFEH design. Furthermore, the energy flow from human walking to the usable energy by the PFEHs and the methods to improve the energy conversion efficiency are presented. …

A significant amount of consumer electronics cannot be switched off completely without being unplugged. Standby power, also known as phantom power, refers to the electric power consumed by electronic appliances when they are switched off. There are some devices that need constant power; items like alarm clocks and security systems need constant power to function correctly. Some devices, such as video game consoles and televisions, consume power without offering any features. Electricity lost from standby power has been increasing with the amount of consumer electronics increasing in households.
This project’s goal is to create a low power remote that can …
