The signal can be converted by piezoelectric films in many ways such as thermal to electrical (temperature sensor), mechanical to electrical (microphone), and electrical to mechanical ( a loudspeaker). The circuit is signal conditioning amplifier for piezofilm sensor which use three op amps and has a high-input-impedance differential charge. Here is the circuit :

This circuit [...]

This is an audio line driver circuit using a TSH22. The advantages of this circuit are low distortion, exhibits a wide bandwidth and an output current sufficient to drive medium impedance loads at a high level modulation. Here is the circuit :

This circuit uses two TSH22 that is used in non inverting mode. The gain [...]
