Force Sensing Resistors were invented in 1977 by Franklin Eventoff, the man that went on to found Interlink Electronics. They are literally the world leaders in FSR technology, and our partner in distributing these in the UK and Europe. Force Sensing Resistors are comprised of a conductive polymer which changes resistance depending on pressure applied, with the more pressure applied, the lower the resistance value.
Force Sensing Resistors for all functions
Force Sensing Resistors are useful in any industry that needs to measure a pressure reading, from checking the liquid content of water storage tanks, through to floor mats designed to assist in teaching injured and disabled people how to walk again. They are even used to measure minor muscle movements to allow for a more natural control over prosthetic limbs.
FSR402 is the standard in FSR technology. At a diameter of 0.5 inches, they are the ideal size to represent fingertips in prosthetic limbs, allowing for fine motor control with accurate pressure reading. As with the FSR400, the FSR402 is available with a short or long tail. The FSR402 has a tail of 38mm.
