Embodiment Construction

[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

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

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

[0048] Electrode pattern: refers to the pattern formed by the electrodes in the electrode layer according to a certain arrangement. In the embodiment of the presen...

Abstract

The invention discloses a touch sensor, a touch event detection method and device and an intelligent robot, and relates to the field of capacitive touch sensors. The touch sensor comprises a first flexible packaging film, at least one layer of flexible dielectric layer film and a second flexible packaging film, and a first electrode pattern is arranged on the first flexible packaging film; a second electrode pattern is arranged on the second flexible packaging film; the flexible dielectric layer thin film is arranged between the first flexible packaging thin film and the second flexible packaging thin film, and the flexible dielectric layer thin film is a thin film with a surface structure; the first electrode pattern and the second electrode pattern are vertically stacked, the first flexible packaging film and the second flexible packaging film package the flexible dielectric layer film, and the positions of the electrodes in the first electrode pattern are in one-to-one correspondence with the positions of the electrodes in the second electrode pattern. All parts of the tactile sensor are made of flexible materials and can be perfectly attached to the outer surface of the intelligent robot, and sensing signals are more stable and accurate.

Description

technical field [0001] The present application relates to the field of capacitive tactile sensors, in particular to a tactile sensor, a touch event detection method, a 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 movement, but also need to sense the external environment and give feedback. Therefore, tactile sensors are usually combined with intelligent robots. [0003] In related technologies, most of the existing intelligent robot systems use commercial hard film capacitive pressure sensors. This kind of tactile sensor includes film capacitive pressure gauges or strain gauges. The robot can detect the pressure of contact. [0004] Based on the above situation, an intelligent robot combined with a tactile sensor can only use a specific part to sense pressure, and cannot realize all-round sensing of an intell...
