Abstract
A sensor device according to an embodiment of the present invention includes an electrode array having plural electrodes arranged in an array manner, a signal generator configured to generate a first signal having a first frequency, and apply the first signal to the plural electrodes, and a detection unit configured to, when the first signal is applied to the plural electrodes, and a second signal having a second frequency is applied to an object to be detected, detect a distance between each electrode included in the electrode array and the surface of the object, using an interference wave between the first signal applied to each electrode and the second signal applied to the object, or detect irregularities on the surface of the object, using a signal generated by using the interference wave outputted from one electrode and the interference wave outputted from another electrode.
