Abstract EN
Force-sensing resistors (FSRs) are inexpensive alternatives to load cells.
They are suitable for applications where noninvasive devices are needed to measure force, stress, or pressure.
However, they have been proved to be hysteresis prone and offer nonrepeatable readings due to their highly voltage-dependent electrical resistance.
A piezocapacitive effect has been found as an alternative phenomenon that is able to offer force-dependent readings of capacitance with less hysteresis error.
Also, this capacitance is not dependent on voltage, which also improves repeatability in force measurements.
Since measuring capacitance is more expensive than resistance, the least costly conditioning circuitry is desired.
An inexpensive alternative using an LM555 that oscillates depending on capacitance is here presented.
Hysteresis and repeatability errors have been reduced for a widespread-used force-sensing resistor brand.
