A Wireless Sensor System for Real-Time Measurement of Pressure Profiles at Lower Limb Protheses to Ensure Proper Fitting

Abstract

The goal of this project is to perform initial development of a new sensor system for ensuring proper fitting of a lower limbprosthesis by providing real-time monitoring of pressure distribution at the body-prosthesis interface. To date, we have completed the design, fabrication, and optimization of the base sensing platform, a three strip sensor. Specifically, we have constructed a sensing layer that can be placed on a hard surface for measuring force loading. To evaluate the efficacy of the sensor, we have also constructed an automated pneumatic mechanical loader and the interface controlling circuits for the loader, an algorithm has been developed. The next step is to develop a the base technology into a grid like mapping sensor, construct the excitation and detection circuits, modify and optimize the algorithm, and embed the sensor.
