The Nano Electromechanical “Squitch”

A MIT graduate student is changing the landscape of electromechanical switches.

Farnaz Niroui, an electrical engineering graduate student at MIT, has developed a squeezable nano electrochemical switch with quantum tunneling functions. Her development combats the longstanding problem of the switch locking in an “on” position due to metal-to-metal contacts sticking together.

The challenge of this permanent adhesion is called stiction, which often results in device failure. Niroui looks to solve this issue by creating electrodes with nanometer-thin separators.

She has effectively turned stiction from a problem into a solution.
