Embodiment Construction

[0042] Such as figure 1 and figure 2 As shown, the structure of the capacitive sliding sensor in this embodiment is as follows: a flexible substrate 7 and a flexible upper substrate 2 positioned directly above the flexible substrate 7 and parallel to the flexible substrate 7 form the frame of the sensor device, and the flexible substrate 7 It is supported by a rectangular column 6 with the flexible upper substrate 2; a through hole is provided in the center of the flexible upper substrate 2;

[0043] On the upper surface of the flexible base 7, there are four rectangular flexible sensing plates 5 that are not in contact with each other arranged in a cross, and a cross-shaped flexible common plate 4 is arranged at intervals directly above the four flexible sensing plates 5. , the four protruding ends of the flexible common pole plate 4 respectively form a parallel plate capacitive sensor with the corresponding flexible sensing pole plate 5 located below it;

[0044] A cylind...

Abstract

The invention discloses a capacitive slide tactile sensor. The capacitive slide tactile sensor is characterized in that a frame of the sensor is composed of a flexible substrate, a flexible upper substrate and rectangle columns; four rectangular flexible sensing pole plates not in contact with one another are arranged on the upper surface of the flexible substrate crosswise, a cross-shaped flexible public pole plate is arranged right above the rectangular flexible sensing pole plates at an interval, and four extension ends of the flexible public pole plate and the corresponding flexible sensing pole plates thereunder form parallel-plate capacitive sensors respectively; a cylindrical feeler lever penetrates the center of the public pole plate, and an anti-slide rubber connector is arranged at the top end of the cylindrical feeler lever. When a target object and the anti-slide rubber contactor generate relative sliding, the cylindrical feeler lever drives the flexible public pole plate to move, and equivalent area of the four parallel-plate capacitive sensors is changed, so that slide tactile information is acquired. The capacitive slide tactile sensor has the advantages of simple structure, high sensitivity and the like.

Description

technical field [0001] The invention belongs to the technical field of sensors, and more specifically relates to a capacitive touch-slip sensor device used for the bionic skin of an intelligent robot. technical background [0002] Robotic tactile sensing technology is one of the key technologies to realize intelligent robots. Tactile sensor is a necessary medium for the direct interaction between the robot and the environment. At present, research on the tactile sense of intelligent robots at home and abroad is mainly focused on the force tactile aspect. Continuously innovating tactile force detection models and optimizing the application of force tactile algorithms on flexible and texture reproduction devices enable these devices to better reproduce virtual scene objects. The tactile characteristics of softness, texture and force, but the research on the perception of slip information is still less. Tactile sensing detection is the key link for intelligent robots to realiz...
