Title:
TACTILE SENSOR AND TACTILE IMAGER
Document Type and Number:
Japanese Patent JPH0755598
Kind Code:
A
Abstract:
PURPOSE: To provide a tactile sensor which enables highly accurate measurement of slight changes in pressure and a tactile imager which enables use thereof on a curved surface at a high accuracy.
CONSTITUTION: A tactile sensor S comprises a beam 21 on a soft substrate 1 and a protrusion part 22 and a strain gauge 23 on the beam 21. It is desired that the soft substrate 1 is a polymer sheet with an elastic modulus of 1-1000kgf/ mm2 and a Shore hardness of 10-100 and a strain gauge 23 is arranged on the beam 21 sandwiching the protrusion 22. In a tactile imager of the invention, a plurality of tactile sensor units as mentioned above are arranged two- dimensionally on the soft substrate preferably at a rate of 1-10,000unit/cm2.
