Embodiment Construction

[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0046] First, the terms involved in the embodiments of the present application are introduced:

[0047] Dielectric layer (Dieletric): refers to a layered structure used to maintain the insulation between lines or conductive layers, and is also named as the substrate. The dielectric layer may be made of insulating material, such as polydimethylsiloxane (PDMS). In the embodiment of the present application, the polydimethylsiloxane is made into a film shape, so that the tactile sensor has good flexibility and can be attached to the outer surface of the intelligent robot.

[0048] Electrode pattern: refers to a pattern formed by electrodes in an electrode layer according to a certain arrangement. In the embodiments of the present applicatio...

Abstract

The present application discloses a tactile sensor, a touch event detection method, device and intelligent robot, and relates to the field of capacitive tactile sensors. The touch sensor includes: a first flexible packaging film, at least one flexible dielectric layer film and a second flexible packaging film; the first flexible packaging film is provided with a first electrode pattern; the second flexible packaging film is provided with a second electrode pattern; The flexible dielectric layer film is between the first flexible packaging film and the flexible second packaging film, and the flexible dielectric layer film is a film with a surface structure; the first electrode pattern and the second electrode pattern are vertically stacked, and the first flexible packaging film The flexible dielectric layer film is encapsulated with the second flexible encapsulation film, and the positions of the electrodes in the first electrode pattern correspond one-to-one with the positions of the electrodes in the second electrode pattern. Each part of the structure of the tactile sensor is made of flexible materials, which can be well attached to the outer surface of the intelligent robot, and the sensing signal is more stable and accurate.

Description

technical field [0001] The present application relates to the field of capacitive tactile sensors, and in particular, to a tactile sensor, a touch event detection method, device, and an intelligent robot. Background technique [0002] With the development of intelligent robot technology and a wide range of applications, intelligent robots not only need to complete the set mechanical movements, but also need to perceive the external environment and give feedback. Therefore, tactile sensors are usually combined with intelligent robots. [0003] In the related art, most of the existing intelligent robot systems use commercial hard film capacitive pressure sensors, such tactile sensors include thin film capacitive pressure gauges or strain gauges. The robot can detect the pressure of the contact. [0004] Based on the above situation, intelligent robots combined with tactile sensors can only use specific parts to sense pressure, and cannot realize all-round sensing of intellige...
