FIELD: physics, communications.
SUBSTANCE: invention relates to an electrostatic capacitive sensor device and can be used for operational input into an electronic device. The device includes a sensor electrode which is provided in multiple positions, a high frequency signal source which feeds a high frequency signal to the sensor electrode through a detector circuit which includes a predetermined impedance element, a wire means which connects the sensor electrode and the detector circuit, a screening means which encircles the sensor electrode and the wire means, and a screen signal source at the input of the detector circuit which feeds a screen signal to the screening electrode.
EFFECT: design of a device with high screening action on electrical noise.
