I want to measure the charge displaced by a force acting on a piezoelectric sensor. The problem is I don't know the sensor so I have no idea how big the current generated by the sensor may be nor what the sensor parameters are (leakage Resistance, parallel Capacitance of sensor).
Does anyone know if there are some pre-made solutions like an IC or something, that can measure the charge and produce an output signal? It does not matter if the output is analog or digital, all I want is a good measurement of my charge and then get an idea how big the applied force is.
I know this is usually done with a charge amplifier, but since I don't know much about the sensor, I would like a already made solution so I can make sure there are no errors in my circuit that influence my measurement.
