1. A touch sensor comprising:
- a contact sensor, including a first electrode and a first switching element connected to the first electrode, configured to detect a change in an electric potential when an object contacts a surface; and
a pressure sensor, including a second electrode and a second switching element connected to the second electrode, configured to detect a change in a pressure when an object depresses the surface, whereina plurality of the contact sensors and a plurality of the pressure sensors are disposed regularly in an array.

Abstract
A touch sensor includes a contact sensor and a pressure sensor. The contact sensor includes a first electrode and a first switching element connected to the first electrode, and detects a change in an electric potential when an object contacts a surface. The pressure sensor includes a second electrode and a second switching element connected to the second electrode, and detects a change in a pressure when an object depresses the surface. The touch sensor includes a plurality of the contact sensors and a plurality of the pressure sensors disposed regularly in an array.

3. A touch pad comprising:
-
a contact sensor configured to detect a contact with an object on the surface of a specific face; and a pressure sensor configured to detect a depression by an object on the surface of the specific face; and a control signal processor configured to generate a control signal based on of a position detected by the contact sensor and a state the detected position has been in contact, or based on a position detected by the pressure sensor and a state the detected position has been depressed; and
to send the control signal to an external device.

4. An input device comprising:
-
a contact sensor configured to detect a contact with an object on the surface of a specific face; a pressure sensor configured to detect a depression by an object on the surface of the specific face; a control signal processor configured to generate a control signal based on a position detected by the contact sensor and a state the detected position has been in contact, or based on a position detected by the pressure sensor and a state the detected position has been depressed; and a display configured to output information in response to the control signal, the information corresponding to the position detected by the contact sensor, or corresponding to the position detected by the pressure sensor. - View Dependent Claims (5, 6, 7, 8)
