How it works

A micromechanical photoswitch that harvests energy from specific infrared radiations to implement abrupt ON/OFF switching without using any electrical power.


World's first sensible sensors

Zepsor offers world's first zero-power infrared sensors with uninterrupted operation and unprecedented accuracy for touchless interfaces, presence detection and many more applications.


Near zero power consumption in standby extends battery lifetime by over 10 times.

High accuracy

True presence sensing that is not fooled by stationery target. And omnidirectional sensing that does not miss an angle.


10 to 100x smaller than conventional active and passive infrared sensors.


Less optics, less circuitry, less cost.
