Title:
SENSOR DEVICE
Document Type and Number:
Japanese Patent JP2018155711
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sensor device of new structure, with which it is possible to realize detection of a worker, etc., by a pressure-sensitive sensor with high accuracy and sufficiently reduce an acting force when the worker, etc., comes in contact with an automatic device.SOLUTION: Provided is a sensor device 10 for detecting contact between a movement unit 18 of an automatic device 12 and a detection object A, the sensor device 10 comprising flexible pressure sensitive sensors 36, 54 for detecting contact between the movement unit 18 and the detection object A. The pressure sensitive sensors 36, 54 are capacitance type sensors having a such structure that each one of telescopically deformable first electrode 42 and second electrode 46 is fastened to either side of an elastically deformable dielectric layer 40, and detecting a pressure acting on facing portions of the first and second electrodes 42, 46 on the basis of a change of capacitance value. An elastic cushion layer 34 is disposed at a position closer to the movement unit 18 than are the pressure sensitive sensors 36, 54, the hardness of the elastic cushion layer 34 being 75% to 500% of the hardness of the dielectric layer 40.SELECTED DRAWING: Figure 2
