Problems solved by technology

Analyzing the research status at home and abroad, it can be seen that the current research on artificial sensitive skin of intelligent robots is limited to either pressure or temperature or pressure-temperature composite type, and the temperature sensing unit of pressure-temperature composite type is a non-flexible sensor.
There is no report on flexible sensor arrays that simultaneously detect three signals of pressure, temperature and humidity

Embodiment Construction

[0015] see figure 1 , figure 2 In this embodiment, the structural form of the flexible composite array sensor used for the artificial sensitive skin of the intelligent robot is: the sensing unit constituting the array is based on a flexible polyimide circuit board, and pressure sensors are respectively arranged on the same surface of the base. 1. The temperature sensor 2 and the humidity sensor 3; the surface height of the pressure sensor is higher than that of the temperature sensor and the humidity sensor, forming an overall concave-convex distribution form (such as figure 2 shown).

[0016] The specific implementation is that under normal temperature and pressure, the pressure-sensitive material is prepared into a small piece with a thickness of about 2mm, and the temperature-sensitive material and the humidity-sensitive material are prepared into thin films by spin coating. The thickness of the film of the temperature sensitive material and the humidity sensitive mater...

Abstract

The invention discloses a flexible compound type array sensor used for the artificial sensitive skin of an intelligent robot, which is characterized in that a sensing unit for forming an array takes a flexible polyimide circuit board as a substrate; the same surface of the substrate is respectively provided with a pressure sensor, a temperature sensor and a humidity sensor; and the surface height of the pressure sensor is higher than those of the temperature sensor and the humidity sensor to form a distribution form which is integrally in a male and female mode. According to the flexible compound type array sensor used for the artificial sensitive skin of the intelligent robot, which is disclosed by the invention, pressure, temperature and humidity can be simultaneously measured, and the flexible compound type array sensor used for the artificial sensitive skin of the intelligent robot has the advantages of good flexibility, high precision and stable performance.

Description

technical field [0001] The invention belongs to the field of sensor technology, and more specifically relates to a sensitive skin flexible composite array sensor applied to intelligent robots. Background technique [0002] The international robotics community is increasing research efforts in scientific research. For intelligent robots, sensors are required to accurately perceive the environment and be soft enough to make robots have the same perception and flexibility as humans. The artificial sensitive skin of the intelligent robot is a modular array sensor with data analysis capability, which covers the surface of the intelligent robot and relies on the composite array sensor on the artificial intelligence skin to perceive the external environment information. With the increasing complexity of the work of intelligent robots, a single tactile sensor can no longer fully meet the needs of actual work. Now the flexible composite sensor with simultaneous detection of multiple ...
