Experimental data for assessing sensitivity degradation in Force Sensing Resistors

This was done to assess sensitivity degradation using: a) An inverting-amplifier circuit. b) A voltage divider circuit. The FlexiForce sensors were tested with circuits a) and b) at multiple sourcing voltages (1.25V; 2.5V; 5V; 7.5V). 16 Specimens of each sensor model were tested at the aforementioned conditions.

Data in the files are organized as follows: Column 1 through 3: Internal use, do not provide valuable information Column 4: Nominal force applied to the sensors. It was used to close the force loops using load cell measurements in the test bench. Column 5: Output voltage from Sensor 1 Column 6: Instantaneous force applied to the sensor at the moment of measuring.
