INPUT DEVICE |
摘要 |
An input device is provided with a film-based pressure sensor build from a first carrier film, a second carrier film and a spacer arranged between the carrier films for keeping them at a distance from one another. The spacer has an opening delimiting an active zone, in which first and second electrodes are arranged in such a way that, in response to a compressive force acting on the active zone, an electrical contact is established between the first and second electrodes. A control circuit able to operate in at least a first and a second mode of operation is configured so as to measure, in the first mode of operation, a quantity indicative of electrical resistance between the first and second electrodes for detecting an amount or a position of a compressive force acting on the active zone and, in the second mode of operation, a quantity indicative of a capacitance for detecting a person or an object approaching thereto. |
