<p>A data input device with a film-based pressure sensor including a first carrier film, a second carrier film and a spacer. The spacer has an opening delimiting an active zone, in which first and second electrodes are arranged such that, in response to a compressive force, an electrical contact is established. A control circuit able to operate in at least a first and a second mode is configured to measure, in the first mode a quantity indicative of electrical resistance and, in the second mode, a quantity indicative of a capacitance.</p> |
