1) What is the output of piezo electric transduser?

2) Which type of piezo electric transduser has the maximum output?

3) How to convert millivolt range into usable voltage range?

The real question is what are you trying to do. Generate Electricity as a power source, Piezo does not deliver the current needed to do this.

To convert to a usable voltage the only way is to is connect it to an operational amplifier. Still requires external power.

Without knowing what you want to do the question is very difficult to answer.

Aside from transducer efficiency, poor coupling of acoustic into mechanical energy is also a problem,
