Biometric sensors for personal devices

Abstract

Methods and systems may provide for a system having a flexible substrate, an ultrasonic transducer array coupled to the flexible substrate and a processor coupled to the ultrasonic transducer array. The processor may identify a fingerprint based on a signal from the ultrasonic transducer array. The system may also include an external component having a curved profile, wherein the ultrasonic transducer array is embedded in the external component and includes a read surface that conforms to the curved profile. In one example, the external component includes a button having a function that is separate from identification of the fingerprint.

Dependencies are inferred from the claim text.
