Abstract
A sensor device includes a capacitive touch panel including a plurality of electrodes, an input device configured such that a resonance circuit including a first conductor and a second conductor is covered with a non-conductor, and a sensor controller. The first conductor and the second conductor are capacitively coupled to at least one of a plurality of electrodes in the touch panel when the input device is disposed on the touch panel or when the input device disposed on the touch panel is operated. The sensor controller is configured to detect positions of the first conductor and the second conductor on the touch panel by applying a voltage to the plurality of electrodes in the touch panel based on a resonance frequency of the resonance circuit.
