Problems solved by technology

Sensitive units such as silicon piezoresistive and silicon temperature made by microelectronics contain extremely fragile silicon diaphragms. Even if they are implanted in the protective layer of polymers, the reliability between the robot and the operating object cannot be guaranteed. The adaptability is poor,

Embodiment Construction

[0022] see figure 1 , figure 2 , the present embodiment is based on a flexible polyimide circuit board as the substrate 1, and a three-dimensional force sensing unit array and a temperature sensing unit array are respectively arranged on the substrate 1, and each three-dimensional force sensing unit 2 in the three-dimensional force sensing unit array And the temperature sensing units 3 in the temperature sensing unit array are arranged at intervals; and the surface height of each temperature sensing unit 3 is lower than the surface height of each three-dimensional force sensing unit 2, forming an overall concave-convex distribution form.

[0023] In specific implementation, the three-dimensional force sensing unit 2 uses carbon black filled silicone rubber as the pressure sensitive material, and is set as a disc-shaped flexible pressure-sensitive conductive rubber; the temperature sensing unit 3 uses carbon fiber filled silicone rubber as the temperature sensitive material, a...

Abstract

The invention discloses a multifunctional flexible touch sensor. The flexible touch sensor is characterized in that a flexible polyimide circuit board is used as a substrate; a three-dimensional force sensing unit array and a temperature sensing unit array are respectively arranged on the substrate; three-dimensional force sensing units in the three-dimensional force sensing unit array and temperature sensing units in the temperature sensing unit array are arranged at intervals; and the surface height of each temperature sensing unit is lower than the surface height of each three-dimensional force sensing unit, thereby forming the integral concave-convex distribution form. The full-flexibility multifunctional touch sensor disclosed by the invention has the advantages of excellent surface adaptability, high three-dimensional force measurement reliability, small cross interference of mechanics and temperature information.

Description

technical field [0001] The invention belongs to the technical field of sensing, and more specifically relates to a multifunctional flexible touch sensor applied to robots. Background technique [0002] The sense of touch is an important sense when a living body is in direct contact with an external object. Through the sense of touch, various physical information of the target object can be obtained, such as the size of the contact force, softness, hardness, elasticity, roughness, temperature, humidity and other sensory information. . Tactile sensors are an important means for intelligent robots to perceive various external information. The multifunctional tactile sensor has multiple sensors and multi-information processing technology in order to obtain more tactile information than a single sensor. As robots begin to enter human's daily life, they will be required to have the same multiple perception capabilities as humans, so it is particularly important to study safe and...
