Research on information acquisition and preprocessing of array force sensor

This paper describes the application of a flexible array force sensor in the field of rehabilitation robot. In order to collect the distribution of man-machine force, a multi-channel array force data acquisition system is designed. In the hardware design, the CD4051B is used to select the channel, and the STM32 micro controller is used for data acquisition and processing. The computer display interface program is written by Microsoft Visual Studio 2013, which realizes the collection, processing, storage and graphical display of sensor data. Experiments show that the data acquisition system has the characteristics of simple structure, friendly man-machine interface, and it has great application value in rehabilitation field.
