Interlink Electronics

Active

Overview

Interlink Electronics develops, manufactures, and sells force-sensing resistor (FSR) technology, including sensors, subassemblies, and modules for human-machine interfaces. Its products support applications in consumer electronics, automotive, industrial, medical devices, IoT, and wearables. The company provides custom engineering services combining materials science, manufacturing, and software.

History

Interlink Electronics was founded in 1984-1985 around patented Force Sensing Resistor technology. It expanded from force-sensing into position sensing, gas sensing, printed electronics, and custom devices. Key milestones include serving Fortune 500 companies since 1985, holding 49 issued patents plus 14 pending, and going public with Nasdaq symbol LINK. In 2006, it filed and later dismissed a patent lawsuit against Nintendo over Wii Remote technology.
