Basic Equations

This paper discusses four types of piezoelectric basic equations, and there are two piezoelectric sensors which are composed of piezoelectric ceramics tightly pasting in the thin-walled structure. They can respectively measure structure of strain and strain rate changes. Based on the description of two kinds of piezoelectric sensors formation, The output display solution and their frequency domain forms are furtherly presented, and the advantages of the sensor are discussed. This conclusion can provide theoretical guidance for structural vibration active control.
