Abstract

The invention discloses a resistance-capacitance tandem type flexible sensor for measuring contact force. The sensor comprises an upper capacitor layer, a conductive elastomer layer and a lower capacitor layer which are stacked together in sequence from top to bottom; the upper capacitor layer sequentially comprises a first upper capacitor electrode, a first dielectric layer and a second upper capacitor electrode from top to bottom; the conductive elastomer layer sequentially comprises a first electrode, a conductive elastomer and a second electrode from top to bottom, and the conductive elastomer is conductive and the resistance of the conductive elastomer changes along with the deformation of the conductive elastomer; the lower capacitor layer sequentially comprises a first lower capacitor electrode, a second dielectric layer and a second lower capacitor electrode from top to bottom; and the first upper capacitor electrode and the second lower capacitor electrode are output ends of the sensor. The flexible sensor provided by the invention has the characteristics of high sensitivity and high measurement accuracy.

Description

technical field [0001] The invention relates to the technical field of flexible sensors, in particular to a flexible sensor for measuring contact force in series with resistance and capacitance. Background technique [0002] With the development of intelligent robot technology, the importance of sensor measurement in the intelligent control of robots is becoming more and more significant. The flexible force sensor has the characteristics of simple structure, low power consumption, impact resistance, and strong overload capacity. At this stage, many flexible force and tactile sensors adopt capacitive structure, that is, the change of external force is converted into the change of output capacitance. The output capacitance and output capacitance variation range of most flexible capacitive sensors are relatively small, which is not conducive to actual measurement. Contents of the invention [0003] The purpose of the present invention is to provide a flexible sensor for mea...
