Did anyone ever replace the mic with a structure-borne sound sensor?

Hi I am planning to do a contact microphone with a piezo film sensor. As this will need some amplification, there are some openquestions coming up. How much current can I daw from the 3V source? Which level of signal voltage should I target to reach the internal preamp after the external amplification? Thank you very much! Jonas
