The basic working principle and basic purpose of piezoelectric sensor are introduced, and two kinds of preamplifiers are described respectively. Both of them are used to amplify the extremely weak signal produced by the piezoelectric sensor. The amplification principles of two kinds of amplifiers are analyzed in detail, and through the comparison of these two amplifiers, their merits and demerits as well as applicable situations are given.
