Abstract

LED-photoresistor mechanical-electrical optoisolator transducers are Polaroid optocouplers specialized in converting rotation/translation movements into electrical signals. The processes standing at the basis of such conversion are: light’s polarization, re-orientation of the polarizing plan and modification of the distance between source and photoreceiver. This device is at the crossroad of three research directions: MEMS, Smart Lighting and that one of sensors and transducers..
