An apparatus and method for measuring a tactile information, using a material having variable pressure dependent properties is disclosed. The apparatus for measuring the tactile information may include a plurality of pressure measurement units to measure a magnitude of an external pressure using a material having variable properties, and a tactile information measurement unit to measure a three-dimensional (3D) tactile information based on the external pressure using a location of the plurality of pressure measurement units and a pressure measured by the plurality of pressure measurement units.

Apparatus and method for measuring tactile information

A flexible tactile sensor apparatus is provided. The flexible tactile sensor apparatus may obtain information about an applied force, using a resistance between an upper nano wire array of an upper plate and a lower nano wire array of a lower plate, which may be changed based on a distance, between the upper nano wire array and the lower nano wire array, adjusted in proportion to the force.
