Founded by the Inventor of the Force Sensing Resistor

Franklin Eventoff, inventor of the Force Sensing Resistor

Franklin Eventoff began developing electronic musical instrument controllers in 1972. Five years later, he invented the force-sensing resistor — a breakthrough that would transform how devices sense human touch.

By 1978, his first product — The Magical Musical Thing — had been licensed to Mattel Toys. Three million were sold. Franklin went on to found Interlink Electronics, bringing FSR technology to Roland keyboards, Akai drum machines, and countless other products across multiple industries.

In 2001, seeking to recapture the spirit of innovation that started it all, Franklin founded Sensitronics. Today, with nearly five decades of expertise, Sensitronics continues to lead the industry in force-sensing technology.
