A Compact Wearable System for Detection of Plantar Pressure for Diabetic Foot Prevention

This paper is aimed to present a pair of wearable shoe-pads with shoes to detect the pressure and the variation of plantar pressure of human body and provide the pressure map with an alarm to the patient. In this work, a complete system is developed which includes data collection circuit, wireless transmission circuit and data analysis. Pressure sensors are employed to collect the data of plantar pressure, send analogue signals to the microcontroller, and a Bluetooth module transmits the data to a PC. Finally, the data is examined and display a hot map of plantar pressure. In addition, by observing the color patterns on a hot map, user or medical staff can judge whether the patient has tendency to develop an ulcer in case of diabetic patient.
