摘要

Accelerometers based on ferroelectrets are lightweight and inexpensive. Their sensitivity and resonance frequency can be adjusted by the d_(33)-coefficient and Young's modulus of the film and by the seismic mass, the static pressure on the film, and the number of films. Presently, sensitivities of more than 20pCs~2/m are available. The accelerometers can be used at extremely low frequencies, since the conductivity of the ferroelectret-films is very low. Furthermore, all measured data are in good agreement with model calculations.
