Electrostatic Swing Energy Harvester

Generation of the electric power by permanently polarized (electret containing) capacitor is analyzed and investigated in the matter of energy harvesting from oscillations and rotation. Experimentally demonstrated the generation of short high-voltage (up to 1 MV) pulses or low voltage (few volts) alternating current that can be rectified and stored.

A broadband vibrational energy harvester

We propose a design for an energy harvester which has the potential to harvest vibrational energy over a broad range of ambient frequencies. The device uses two flexible ceramic piezoelectric elements arranged in a buckled configuration in the absence of vibrations. Experimental data show that this design allows enhanced harvesting of energy relative to a comparable cantilever design, both for ...

Flexible substrate electrostatic energy harvester

Energy harvesting is attractive for powering wireless sensors, especially in applications such as body sensor networks and pervasive sensing, where power source replacement or recharging is impractical. A MEMS (micro-electro-mechanical systems) electrostatic harvesting device suitable for body motion has been reported previously, using a rolling rod as the proof mass. A new rolling rod device i...

A Hip Implant Energy Harvester

This paper presents a kinetic energy harvester designed to be embedded in a hip implant which aims to operate at a low frequency associated with body motion of patients. The prototype is designed based on the constrained volume available in a hip prosthesis and the challenge is to harvest energy from low frequency movements (< 1 Hz) which is an average frequency during free walking of a patient...
