I'm doing a project on the field of biomedical engineering and my goal is to produce/or acquire a piezoeletric sensor to measure the respiration signal and integrate it in the Arduino.
Can you enlight me on how to connect such 'raw' sensors to my board to do the signal acquisition? Is any pre-processment required? Or just a breadboard will do?
The wires from the beeper were connected to the input of a custom-built data-acquisition system (CMCdaq) to record respiratory movements
so it's not going to be simple. The signal from the sensor will be very small and need amplifying in some way.
The first step would be to get hold of one of these 'beepers' and connect it to a sensitive voltmeter, then see what sort of voltage levels you can get out of it. Also need to measure its internal resistance. With that information, someone experienced with op-amps could probably suggest a suitable circuit.

(Yes I'm a begineer in this community )
Any sort of answers will be appreciated.
Search for "aircraft oxygen". One of the companies you find will have a system that monitors breathing. You might contact them for information. The sensor is patented, but they may help you.
