Abstract :
An electrostatic micro-power generator (MPG) designed to power wireless sensors is presented. The MPG does not need an initial charge source and produces 9µW using a 0.5g vibration source. The MPG is also characterized by wide energy collection band that can reach up to 10Hz. Optimization of a prototype shows the possibility of generating more than 190µW. A non-linear model for the proposed MPG is presented. The simulation results obtained from the model shows good agreement with the experimental results.
