Hi there,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.
Such sensores can be made as sugested:

or even removed from a greetings card that plays music upon unfolding
piezo buzzer - How are electronic musical greeting cards made? - Electrical Engineering Stack ExchangeCan 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?
(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.
