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 [...]

These are circuits of high impedance low capacitance buffer and high impedance low capacitance  amplifier. First figure is a high impedance low capacitance buffer circuit, it uses the 2N446 JFET that features low input capacitance. The feedback buffer a wide-band unity gain amplifier is made from this 2N446 JFET. Here is the circuit :

The second [...]

This is an ultra high input impedance AC unity gain amplifier circuit. This circuit is used to get unity gain from ultra high input impedance AC. Here is the circuit:

Because we can’t reduce input capacitance of this circuit, so we use the 2N4416 which has low capacitance. It is operated as a source follower with [...]

Silicon pezoresitive-bridge pressure transducer (SPPT) is very popular in medical, industrial, environmental, and automotive pressure sensor application. The general architecture of SPPT uses a thin micromachined silicon diaphragm incorporates a implanted piezoresitive Wheatson-bridge strain-gauge.
The transducer design allows only a small diaphragm deflection sin it has limited elasticity, and this produces only a very small output [...]

Photovoltaic transducers has been widely used in medical, consumer, scientific instrumentation, and industrial applications. Photovoltaic sensors is a solid-state devices and available for wide range of wavelength response, cover from infrared, visible, and ultraviolet spectrum. This characteristic make this type of transducer applicable in diverse jobs such as colorimetry, chemical spectral analysis, non-contact thermometry, non-invasive [...]
