Continuous elastic tactile sensor and detection method thereof

Abstract

The invention discloses a continuous elastic tactile sensor and a detection method thereof. The continuous elastic tactile sensor comprises a first elastic conducting layer, an elastic insulating layer and a second elastic conducting layer which are sequentially arranged in a stacked mode from top to bottom. At least one input signal line is arranged in the center of the first elastic conducting layer, at least two output signal lines are arranged on the edge of the second elastic conducting layer, and output resistors are connected to the output signal lines in series. The continuous elastictactile sensor provided by the invention adopts an elastic material for preparing a sensor, has better adaptability to the surface of a flexible and elastic deformation object, and does not influencethe deformation of a measured surface; the structure is greatly simplified while the contact position and the pressure intensity of a measured surface with a large area are detected, the number of needed signal leads is extremely small, and arrangement is facilitated and influences on deformation of a measured object are avoided.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a continuous elastic tactile sensor and a detection method thereof. Background technique [0002] Touch detection is currently a hot topic in the field of robotics, and it is the physical basis for whether a robot is intelligent. One research direction of touch detection is to make the detection more sensitive and the resolution higher; another research direction is to make the structure simpler and the detection range wider. [0003] Currently, there are many methods for detecting pressure signals, and the principles are various. For example, piezoresistive pressure detection is detected by pressure-induced resistance changes; piezoelectric pressure detection is detected by pressure-induced material release of micro-current; piezo-capacitive pressure detection is detected by changes in the capacitance of capacitors caused by pressure. When pressure sensors are used to obtain position in...
