Title:
PROXIMITY AND TACTILE SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/012329
Kind Code:
A1
Abstract:
The purpose of the present invention is to minimize the elements and substrates composing a sensor and make non-contact detection of the proximity of an object and detection of applied external force possible in the same installation area. A proximity and tactile sensor 10 according to the present invention is provided with a main body unit 11 attached to a region for detection and a detection unit 12 for detecting an approach distance of an object in relation to the main body unit 11 and the magnitude of the external force acting on the main body unit 11. The main body unit 11 is provided with an electrode 14 comprising an electrically conductive rigid body, a magnetic body 15 that is integrally attached to the electrode 14, foam 16 that is disposed outside the electrode 14 and magnetic body 15 and comprises an elastic body, and a magnetic sensor 17 for detecting variation in the magnetic field between the magnetic sensor 17 and the magnetic body 15. The detection unit 12 is provided with a proximity sensing unit 22 for determining the approach distance from variation in the capacitance of the electrode 14 and an external force sensing unit 23 for determining the external force acting on the foam 16 on the basis of the detection by the magnetic sensor 17.
