We present the first micromachined rotational electret power generator, linearized theoretical model of electret power generation, and novel method to produce uniformly charged electret. We also improved our previously developed [1, 2] thin film Teflon AF 1601-S electret technology with respect to dielectric thickness, charge uniformity, and processability. In demonstration, our prototype power generator successfully generated > 25μW with electret thickness of 9μm, effective charge density of -2.8 x l0^-4 C/m^2, and rotational speed of 4170 RPM.
