(OP)
i want to amplify the voltage acquired from a piezoelectric transducer , what is the best possible circuit for such a purpose. i mean should i use a trnsistor or an op-amp, if so the could anyone please tell me the model no of then op-amp that i should use.
i also want to know that which transducer or sensor should i use to to obtain a 3V or higher potential difference on application of a very small mechanical force on the transducer (by small i mean , the force that we use in touchscreen devices)

Use a touchscreen, of course...

Its input impedance is necessarily so high that baking the input cable makes a difference. I'm guessing that the layout and material selection also makes a difference, so you might be better off just buying it as a module instead of building it.
