Portable Human Information Integration System for Evaluation Plantar Force

In this paper, to develop human movement information collecting system with SD card as storage medium. To establishes the human body and computer´s relation. The hardware design of the system with PIC32MX microcontroller and the advantages of data recording using SD card are presented. To acquire 6-channel transducer signal to record SD card through serial peripheral interface were reviewed and analyzed on computer. Using this system union related transducer that may prompt and accurate gathers the human body movement information. Then, carry on the experiment with piezoelectric polymer film transducer in soles, the results show that the development system can be used for evaluation plantar force. Secondary development on the basis of the data acquisition platform can be applied to the training of recuperating one´s health, physical training, sport training, surface EMG and so on.
