These sensors were designed to utilize the fact that the measured signal from piezoelectric sensing elements are strongly influenced by the interfacing circuitry used. A simple analysis is also presented to show that the acceleration rate signal reveals the arrival of a realistic shock earlier than that of the acceleration signal. An experimental setup designed to verify the early detection behavior of acceleration rate sensors versus that of the accelerometers is also described. Factors that have a strong influence on the performance of acceleration rate sensors especially the base strain effect were studied by using finite element analysis as the basis for the main design and principle needed to fabricate an acceleration rate sensor. © 1995 by National Taiwan University.Finite element method; Piezoelectricity; Structural dynamics; Acceleration measurement; Actinium; Aerospace engineering; Design; Elastic moduli; Finite element method; Networks (circuits); Numerical analysis; Performance; Piezoelectric devices; Sensors; Strain; Acceleration rates; Acceleration signals; Measured signals; Piezoelectric sensors; Sensing elements; Simple analysis; Strain effect; Test structure; Acceleration; Accelerometers; Acceleration rate signal; Base strain effect; Interfacing circuitry; Piezoelectric acceleration rate sensors; Piezoelectric strain charge constantInnovative piezoelectric acceleration rate sensorsconference paper10.2514/6.1996-14362-s2.0-0029702777https://www.scopus.com/inward/record.uri?eid=2-s2.0-0029702777&doi=10.2514%2f6.1996-1436&partnerID=40&md5=9f922ce02cc38f21771a7fab16382eea
