About Sensitronics

Founded by the inventor of the Force Sensing Resistor, Sensitronics brings nearly five decades of innovation to every sensor we build.

Sensitronics is a leading provider of electronic force sensor technology. Founded in 2001 by Franklin Eventoff, inventor of the force-sensing resistor, Sensitronics aims to make the devices in our lives more interactive and expressive with innovative membrane sensor solutions that are cost-effective and easy to integrate.

We've delivered hundreds of custom sensor designs to clients representing a wide range of industries, from medical and automotive to music and wearables.

With our on-site laboratory and global network of experienced manufacturing partners, Sensitronics is ready to assist with any or all phases of sensor design and manufacture. We also stock tools like our unique XactFSR materials that empower customers to implement and quickly iterate on their own sensor designs.

Meet the Team

Franklin Eventoff

President, CEO, Director of Technology and New Product Design

Franklin Eventoff began developing electronic musical instrument controllers in 1972. Five years later, with the goal of making electronic musical instruments more expressive, he invented the force-sensing resistor (FSR).

By 1978, his first musical product — The Magical Musical Thing — had been licensed to Mattel Toys. Three million were sold. The following year, the XYZ digitizer pad was invented.

Franklin founded Interlink Electronics in 1985 to further the development of the FSR. While President and CEO, he initiated the use of FSRs in Roland keyboards, Akai drum machines, KAT and Simons drums, Oberheim keyboards, and many other products. Interlink received the California Governor's Award in 1986 for the most innovative product, and in 1987 Franklin received the prestigious international IR 100 award for the development of the FSR.

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