Capacitive sensor for multiple applications measures values that influence the capacitance of a measurement space by measuring the capacitive coupling between two electrodes and relating it to a physical value

Abstract: Method for capacitive measurement of measurement values that influence the capacitance of a measurement space, whereby the capacitive coupling between two electrodes is measured. Measurement is achieved by generating an alternating electrical field in a measurement space using a transmission electrode to which an alternating voltage is applied and a receiving electrode that generates a displacement current in a measurement circuit. The invention also relates to a corresponding device and applications of the inventive method and device.

Sensor device for generating signals that are indicative of the position or change of position of limbs

Abstract: The invention relates to a sensor device for generating electronic signals which as such provide information on a position in space, and/or the movement of limbs, especially of the hand of a user in relation to the sensor device. Said electronic signals can be used to carry out input processes in data processing devices, communication devices and other electric devices. The aim of the invention is to devise ways of generating, in an especially advantageous manner, signals that are indicative of the position and/or the movement of limbs. A sensor device for generating electrical signals which as such provide information on the position or movement of limbs in relation to a reference area comprises a transmitter electrode device (G 1 , G 1 a , G 1 b ), a voltage generator for supplying the transmitter electrode device (G 1 , G 1 a , G 1 b ) with an alternating voltage of a first receiver electrode device, a second receiver electrode device, and a measurement circuit for detecting a field bridging effect towards the receiver electrode devices, said effect being correlated with a movement of the hand or the finger, a screening electrode device (S) at least substantially screening the transmitter electrode device (G 1 , G 1 a , G 1 b ) and/or the receiver electrode device (M 1 , M 2 ) from the measurement circuit with respect to field electrical effects.
