Force-sensing resistors (FSRs) are inexpensive alternatives to load cells. Force Sensing Resistors, commonly known as FSRs, were created back in 1977 with the sole purpose of making electronic musical instruments more expressive.What started out as a product created for strictly one industry has skyrocketed, opening up thousands of different application opportunities in the process. The more appropriate name would be pressure-sensitive resistor. So far I only knew them with 2 PINs: but these products are already equipped with 4 PINs, of which the PIN printed with the manufacturer's label has so far been of no importance for signal transmission. Force sensing resistor or we call force sensor, can be defined as a special type of resistor which exhibits a decrease in resistance with an increase in the force applied to the active sensing surface.

Various off-the-shelf sensors are available for evaluation and prototyping. FSR’s are usu­al­ly com­posed by two sub­strate lay­ers. You can use this program to control all kinds of other functions, in this case to switch on and off an LED. However, they have been proved to be hysteresis prone and offer nonrepeatable readings due to their highly voltage-dependent electrical resistance. The harder the force, the lower the resistance. They are simple to use and low cost. 2. In this example you will be using the FSR sensor as a toggle switch. You will have to add a LED with a resistor … As their name implies, force sensing resistors use the electrical property of resistance to measure the force (or pressure) applied to a sensor.

Today we are dealing with 2 Force Sensing Resistors (FSRs) from Interlink Electronics - known among other things for its FSR402.. Among the most outstanding errors of this type of sensors are the hysteresis, non-linearity and drift errors. This is a force sensitive resistor with a square, 1.75x1.5", sensing area. Figure 2 Force Sensing Resistor with Pull Down Resistor. The force sensing resistor is generally supplied as a polymer sheet or ink which is applied as screen printing. It is used in sensing touch, weight, and any entity characterized by change in mechanical force. FSRs are piezoresistive sensors that use two sets of electrically distinct interdigitated fingers printed on a conductor substrate. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ.
