Tactile Array Sensor with Piezoresistive Cantilever Embedded in Air Cavity

Abstract

In this paper, we proposed array of cantilever to increase sensitivity of a Piezoresistive tactile sensor. As in conventional tactile sensor there is four cantilevers is embedded in air cavity. We formed an array of 2*2 of conventional sensing element which is embedded in air cavity. In this paper we simulate the array of cantilevers by which we confirmed that sensitivity is increased by 20 times. Tactile sensor is used in the area of robotics, manipulating objects and robot-hands is one of the main studies. To achieve exploitation with optimum pressure, as the human does, it is essential to compute as well as apply the pressure, which occurs between the target object and the robot-hands.
