Design of a Triaxial Piezoelectric Accelerometer

Integrated Ferroelectrics, 2003
A monolithic MEMS triaxial accelerometer based on piezoelectric lead zirconate titanate (PZT) thin films with highly symmetric quad-beams and a seismic mass, has been designed and simulated. Theoretical and numerical models for this structure are presented.

Piezoelectric-Ceramic Biaxial Accelerometer

Japanese Journal of Applied Physics, 1993
A new type of biaxial accelerometer using a piezoelectric ceramic cylinder with a plural of strip electrodes has been developed. The sensitivities of the X and Y axes of this accelerometer are about 14.6 pC/G, and the crosstalk of the two axes is below 0.7 pC/G. Frequency characteristics spread from 10 to 1000 Hz (±1 dB).

High sensitivity piezoelectric accelerometer

Review of Scientific Instruments, 1975
A high-sensitivity piezoelectric accelerometer has been developed to monitor and characterize low-level vibration spectra in large structures. The theory of accelerometer design is traced and applied to a specific problem to develop a set of design criteria. The construction and calibration of the accelerometer is described.
