Abstract: Examples of the disclosure are directed to the use of one or more piezoelectric (PE) transducers for detecting one or more touches on a surface. In some embodiments, the one or more PE transducers can complement a capacitive touch sensor array and provide a confirmation that a touch has in fact occurred, and can provide a secondary determination of touch location. In some examples, the one or more PE transducers can be formed on, or as part of, a flex circuit that is adhered to a housing or other structure to which the touch surface is affixed. The flex circuit can be formed as a strip upon which the one or more PE transducers are attached, and can be shaped and sized (optionally with a fold to create a tail for electrical connections) to adhere to an inner or outer surface of the housing.
