Abstract

The invention provides a preparation method of robot flexible touch control material. Firstly piezoelectric ceramic powder and conductive polymer powder are mixed to be ground and dispersed and then evenly laid between upper and lower polyimide films, the 1mmx1mm array mode is formed by controlling the concussion frequency, and the flexible touch control film composite material is acquired by appropriate heating and calendering formation. According to the technology, the common piezoelectric ceramics is used as a pressure sensor, and the effect of connecting the piezoelectric ceramics and conducting charges can be realized by selecting the conductive polymer so that the pressure signals of 1mm2 resolution can be acquired; besides, the whole sensing equipment has flexibility, low preparation cost, stable signal acquisition, great material environment stability and long service life.

Description

technical field [0001] The invention relates to the field of piezoelectric ceramic polymer composite materials, in particular to a method for preparing a robot flexible touch control material. Background technique [0002] Tactile is an important form of perception second only to vision for robots to obtain environmental information, and it is a necessary medium for robots to directly interact with the environment. Among them, flexible tactile sensors have the potential to acquire two-dimensional information on the surface shape of objects. As early as 2003, the research team of the University of Tokyo in Japan made a thin film of pentacene molecules, a low-molecular organic substance, and realized the electronic skin sensing pressure through the pressure sensors densely covered on its surface. With the deepening of scientific research on cutting-edge materials, special materials such as graphene and carbon nanometers are considered by scientists to be excellent "substrates...
