    Abstract: In a data-input device (4) an actuator element (6) that can be manually actuated, and a sensor (9) mechanically coupled to the actuator element (6). The sensor (9) is formed in a body (10) of semiconductor material housing a first sensitive element (11), which detects the actuation of the actuator element (6) and generates electrical control signals. The first sensitive element (11) is a microelectromechanical pressure sensor, formed by: a cavity (24) made within the body (10); a diaphragm (25) made in a surface portion of the body (10) and suspended above the cavity (24); and piezoresistive transducer elements (26) integrated in peripheral surface portions of the diaphragm (25) in order to detect its deformations upon actuation of the actuator element (6).

    Abstract: In some examples, techniques are provided for quick haptic feedback, without the use of a controller, which is local to individual, non-actuating keys, such as keys of a thin keyboard or keypad. The haptic feedback may be in the form of a simulated “key-click” feedback for an individual key that is pressed by a user such that the finger used to press the key feels the tactile sensation. The haptic feedback mimics the tactile sensation of a mechanical key (e.g., buckling spring, pop-dome key switch) to give a user the perception that they have actuated a mechanically movable key.

    Abstract: Examples provide a piezoelectric energy harvester and a wireless switch including the same. The piezoelectric energy harvester includes a pressure transmission part situated between a pressing plate and a piezoelectric body, so as to transmit a uniform amount of pressure to the piezoelectric body, thereby generating a constant level of energy. In addition, a wireless switch uses energy generated in the piezoelectric energy harvester as its driving power, thereby transmitting radio frequency (RF) communications signals to an external electronic device to control the operation of the electronic device.
