摘要：
The foot plantar pressure distribution (FPPD) is time-varying in walking process, and study on foot plantar pressure distribution can help us analyze walking gait, which plays a key role in the research field of wearable device and auxiliary medical diagnosis. Especially for patients with leg or foot movement dysfunction, FPPD can help doctors to make scientific medical diagnosis results. As the foot plantar surface is irregular and flexible, it increases the difficulty of pressure distribution measurement. In this paper, an arrayed pressure-sensitive sensor is utilized to convert the pressure signal to resistance signal, and the resistance signal is then converted to numerical signal by embedded signal processing system based on CC2530. At last, the data of FPPD is uploaded to computer via wireless ZIGBEE network. Based on the proposed system, experiments are conducted on several people to analyze the FPPD in different gaits, including the standing status and walking status; and the experiment results validate this novel wireless FPPD measurement system.
