Abstract :
The use of electrostatic forces in micromechanical systems is well known, but quite high voltages are needed to produce usable forces. In this perspective paper, a 1.5-V battery-supplied integrated circuit able to drive an electrostatic micromotor is presented. The application-specific integrated circuit (ASIC) can output signals up to 80 V, with low-voltage controlling signals. It is especially designed for portable (wristwatch-like) applications. High voltage can be produced by either switching or charge-pumping power supplies
