Both the electrically conducting and non conducting particles are present on this sensing film. They also vary some from sensor to sensor perhaps 10.

The force sensing resistor is generally supplied as a polymer sheet or ink which is applied as screen printing.

Force sensing resistor principle. When there is no pressure the sensor looks like an infinite resistor open circuit as the pressure increases the resistance goes down. The big difference is that pressure is a scalar quantity while force is a vector. As weve said the fsrs resistance changes as more pressure is applied.

These particles are generally sub micrometre sizes which are formulated for reducing the temperature dependence and also for improving mechanical properties increasing. Force sensing resistors contain a conductive polymer film that changes its resistance in a predictable manner when force is applied on its surface. Fsrs are basically a resistor that changes its resistive value in ohms w depending on how much it is pressed.

This video describes the operation of force sensing resistors and how to interface them to microcontrollers using an adc channel. As we discussed in a recent blog post the history of robotic force sensing starts with the development of pressure sensors. These are mechanical pressure sensors.

These sensors are fairly low cost and easy to use but theyre rarely accurate. Force sensors and pressure sensors are two sides of the same concept because pressure is force over area.

The most basic force sensor is a simple force sensitive resistor. So basically when you use fsrs you should only expect to get ranges of response. While fsrs can detect weight theyre a bad choice for detecting exactly how many pounds of weight are on them.

This graph indicates approximately the resistance of the sensor at different force measurements. A led pressure display and a toggle switch circuit is covered. The working principle of a force sensing resistor is based on the property of contact resistance.

A force sensing resistor is a material whose resistance changes when a force pressure or mechanical stress is applied. Hence these are termed as fsr sensors force sensing resistor is a combination of resistor and sensor technology. Force sensing resistor works on two principles first one is percolation in which conductive polymer material particles move and filter and second one is quantum tunneling in which conductive polymer material particles passes through potential barrier that is not so much difficult.

They are also known as force sensitive resistor and are sometimes referred to by the initialism fsr.
