Piezoceramics used in accelerometers are usually chosen because of their high charge or voltage sensitivity, stable temperature curve and low aging rate. Transverse sensitivity is a rather disturbing factor and can be diminished by special construction and careful mounting. Although primarily of interest regarding manufacture of accelerometers, dependence between mechanical properties of piezoceramics and transverse sensitivity has not been systematically tested. This report is based on several tests accompanied by means of commercial available accelerometers. Results indicate whether the right choice of ceramics can improve the quality of accelerometers.
