Vibration energy harvesting typically involves a mechanical oscillatory mechanism to
accumulate ambient kinetic energy, prior to the conversion to electrical energy through a …

A rotational energy harvester for human body applications is presented in this paper. An
oscillating mass, similar to those found in wristwatches is used as a proof mass to act on a …

After being niche markets for several years, application markets for one-chip integration of
large DRAMs and logic circuits are growing very rapidly as the transition to 0.25/spl mu/m …

This paper introduces an impulse excited piezoelectric energy harvesting prototype. The
device is aimed at large amplitude, low frequency excitation typical of human body motion. A …

Energy harvesting is an emerging technology that derives electricity from the ambient
environment in a decentralised and self-contained fashion. Applications include self …

This paper uses a numerical implementation of analytical models to directly compare two
forms of impact-based frequency up conversion technologies: coupled-motion harvesting …

Converting a lower driving frequency to a higher generating frequency has been shown to
increase power outputs of low frequency vibrational energy harvesters. This approach …
