Abstract

A tactile sensor for curved surfaces applicable to objects with multi-dimensional curvature and a small radius of curvature and a manufacturing method thereof are disclosed. The tactile sensor for curved surfaces includes a lower pattern including a plurality of lower polymer film layers spaced at specified intervals in a lower direction, lower metal layers disposed on the lower polymer film layers, and a number of lower resistors disposed on the lower metal layers, an upper pattern including a plurality of upper polymer film layers spaced at specified intervals in a direction perpendicular to che lower direction, upper metal layers disposed on the upper polymer film layers, and a number of upper resistors disposed below the upper metal layers to be electrically connected to the lower resistors, and a lower polymer layer and an upper polymer layer to bond the lower pattern and the upper pattern to each other.

Description

technical field [0001] The present invention relates to a tactile sensor and a preparation method thereof, more particularly to a tactile sensor for a curved surface and a preparation method thereof, wherein the tactile sensor is formed on an upper film and a lower film having excellent bending characteristics and high restoring force, respectively. The metal layer and the resistance layer, and the upper film and the lower film are vertically bonded to each other, thereby enhancing the flexibility to be suitable for objects with multi-dimensional curvature and small curvature radius. Background technique [0002] Recently, haptic functions to obtain information about the surrounding environment through touch, for example, contact force, vibration, surface roughness, thermal conductivity versus temperature change, etc., have been used for advanced information acquisition. A biomimetic tactile sensor capable of replacing tactile perception may be used for microsurgery of blood...
