Abstract :
Two piezoelectric sensor effectiveness coefficients that provide a quantitative measure of effectiveness for piezoelectric materials which are being used for sensing strain (voltage sensor), or strain-rate (current sensor) are introduced. The use of these coefficients for selecting sensor materials is illustrated through a numerical example
