Abstract:
We developed an electrostatic micro power generator for low frequency energy harvesting applications. This micro power generator consists of a new vibration structure and new electret electrode. The advantage of this micro power generator is the high power generation structure of both the controlled gap
between electrodes and long-range moving at low frequency. This generator shows 40+W of power output at very low frequency vibration (2Hz, 0.4G).

ADVANCED ELECTRIC GENERATOR & CONTROL FOR
HIGH SPEED MICRO/MINI TURBINE BASED POWER SYSTEMS

INTRODUCTION

High-speed micro-turbines and mini-turbines play a significant role in the Distributed
Power Systems that provide dependable electric power close to the user. Several high-speed
turbo-generators manufactured by various corporations are now available in the 30 kW to 90 kW
range. These systems operate at speeds from 50000 RPM to 120000 RPM. The generator is
directly coupled to the turbine ....etc

Micro turbines are becoming widespread for distributed power and combined heat and power applications. They are one of the most promising technologies for powering hybrid electric vehicles. They range from hand held units producing less than a kilowatt, to commercial sized systems that produce tens or hundreds of kilowatts.Part of their success is due to advances in electronics, which allows unattended operation and interfacing with the commercial power grid. Electronic power switching technology eliminates the need for the generator to be syn ....etc

For today’s electronics devices the main limiting factor is the battery there is not just enough energy for a given size and weight. As a result of the research in this field have yielded micropower generators recently. They offer higher energy storage densities. The main types are micro engine, which is the shrinked form of an internal combustion engine, thermo electric generator which generates electricity based on seeback effect, microreformers which reform hydrogen and advanced mini fuel cells which generates energy by oxidation rea ....etc

On the macro scale, feedback control is routinely applied to improve performance and enable new tasks in complex and uncertain systems operating in noisy environments. Our lab has focused on applying feedback control ideas to systems on the micro scale. Here we show how control methods can improve existing performance in the UCLA lab-on-a-chip electrowetting system and can create entirely new capabilities in our 'micro fluidic tweezers' cell steering devices.In the Electro-Wetting-On-Dielectric (EWOD) system developed at UCLA by CJ Kim, a grid ....etc
