Bionic skin three-dimensional force touch perception device and measuring method thereof

Abstract

The invention relates to a bionic skin three-dimensional force touch perception device and a measuring method of the bionic skin three-dimensional force touch perception device. The bionic skin three-dimensional force touch perception device comprises a shell, a unit upper layer, a unit basic level and a circuit module. The measuring method comprises the following steps that dynamic data signals are collected to an MCP3208 chip; analog signals are converted into digital signals after entering the MCP 3208 chip; the digital signals enter an EP10K250A chip and are output after being calculated and analyzed; the output signals enter a CY7C68013 chip and then are sent to an upper PC through a USB interface, and LabView virtual instrument software is operated to calculate the forced magnitude and the forced direction of each sensitive unit; eventually the forced situation is stacked to a skin model. The bionic skin three-dimensional force touch perception device and the measuring method of the bionic skin three-dimensional force touch perception device stimulate the multilayer structure of the real skin, and conducting square blocks are arranged annularly referring to a clock, so that accuracy of direction representation is improved. Besides, an electromagnetic shielding layer is imported, so that electromagnetic insulation protection is formed, and measuring efficiency and accuracy are effectively improved.
