Abstract
Facilitating live fingerprint detection utilizing an integrated ultrasound and infrared (IR) sensor is presented herein. A fingerprint sensor can comprise a first substrate comprising the IR sensor, and a second substrate comprising an ultrasonic transducer. The second substrate is attached to a top portion of the first substrate, and a temperature output of the IR sensor facilitates a determination that a fingerprint output of the ultrasonic transducer corresponds to a finger. The IR sensor can comprise polysilicon comprising a thermopile and an array of photonic crystals thermally coupled to the thermopile.
