Abstract

The invention discloses an artificial skin comprising a signal acquisition part and a rear-end circuit. The signal acquisition part comprises at least one detection unit. The detection unit comprisesa humidity sensitive material layer, a piezoelectric material layer and a first electrode which are arranged from the top to the bottom in turn. A second electrode and a third electrode which have thethermal sensitive effect and are arranged in a spaced way are arranged between the piezoelectric material layer and the humidity sensitive material layer. The second electrode, the piezoelectric material layer and the first electrode form a first pressure detection group together. The third electrode, the piezoelectric material layer and the first electrode form a second pressure detection grouptogether. The second electrode and the third electrode respectively act as a first temperature detection group and a second temperature detection group. The second electrode, the third electrode and the humidity sensitive material arranged between the second electrode and the third electrode form a humidity detection unit together. The invention also discloses a pressure, temperature and humiditydetection method through the artificial skin. The artificial skin is simple in structure, high in detection accuracy and suitable for the technical field of artificial intelligence.

Description

technical field [0001] The invention belongs to the technical field of artificial intelligence and relates to an artificial skin, in particular to an artificial skin and a method for detecting pressure, temperature and humidity thereof. Background technique [0002] With the rapid development of robotics and electronic medical technology, artificial intelligence skin has received extensive attention. Artificial intelligence skin is a product that uses functional materials to imitate human skin.
