We consider a battery-less real-time embedded system equipped with an energy harvester. It scavenges energy from an environmental resource according to some stochastic patterns. Because of technical constraints, the harvester device first buffers the harvested energy into a reservoir; then, at regular time intervals, the buffered energy is transferred to a super-capacitor. The success of jobs i...

This paper presents the integration of a novel mechanical torsion spring regulator into pendulum energy harvester system. was designed to provide same voltage-smoothing benefits flywheel without start-up issues caused by increasing system inertia. In addition, introduction between input and output stages device acts as buffer for any sudden impacts, which not only allows from such events be ful...

In this work, we have proposed and experimentally validated of hybrid electromagnetic and triboelectric energy harvester using dual Halbach magnets array excited by human handy motion. Hybrid electromagnetic (EM) and triboelectric (TE) generator that can deliver an output performance much higher than that of the individual energy-harvesting unit due to the combination operation of EM and TE mec...

Wearable electronics require a sustainable electrical power supply to operate. Energy harvesting techniques can be used to convert available nonelectrical energy sources into electrical energy. This paper presents WE-Harvest, a new wearable energy harvesting system that combines the piezoelectric and electromagnetic energy harvesters for wearable devices. Regular human body motions, such as mov...
