Abstract: A mechanism is described for facilitate dynamic and seamless breath testing at computing devices according to one embodiment. A method of embodiments, as described herein, includes detecting air exhaled by a user into a first computing device, where the air includes breath associated with the user. The method may further include sensing the breath in the air, obtaining a sample of the breath, and evaluating the sample, and generating a message based on the evaluation of the sample. The method may further include presenting, via one or more output components, the message to the user via a user interface, where the message includes results of the evaluation of the breath sample.

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.
