Title:
TACTILE SENSOR, ROBOT USING TACTILE SENSOR, MEDICAL DEVICE, AND TACTILE FEEDBACK DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/120302
Kind Code:
A1
Abstract:
A tactile sensor according to the present invention comprises: a base material; a light source unit positioned on the base material; a light reception unit positioned on the base material; and a tactile unit composed of a flexible porous body and positioned on the light source unit and the light reception unit. The flexible porous body has a network-type phase separation structure, and is provided with a three-dimensional mesh-like skeleton and connected pores formed by the skeleton. The size of the pores is 1-100 times larger than the size of the skeleton. The size of the skeleton is 100 nm to 50 μm. The light source unit emits light having a wavelength of 380 nm to 3 μm. The flexible porous body scatters light emitted from the light source unit. The light reception unit receives the scattered light scattered by the flexible porous body. The intensity of the scattered light is gradually reduced as the flexible porous body is compressed.
