Abstract
A dual-function transducer for a force-sensitive multi-touch screen, including a first substrate, at least one electrode array formed on the first substrate, the at least one electrode array including first and second electrodes, and circuitry operatively coupled to the first and second electrodes. The circuitry is configured to measure first and second electrical properties of the electrode array, the first and second electrical properties corresponding to touch and strain, respectively.
