Smart Sensing and Dynamic Fitting for Enhanced Comfort and Performance of Prosthetics

Abstract

The objective of the project is to enhance the long-term fit and performance of prosthetic sockets through smart sensing, adaptive interface, and shear-based dynamic fitting strategy. In the first year, we focused on developing the antenna pressure/shear sensors and the bubble actuators for pressure regulation. An antenna sensor that is capable of measuring shear and pressure displacements simultaneously was designed, fabricated, and validated. Three different test fixtures and associated control software were developed for sensor calibration. Fabrication techniques were developed for implementing flexible sensors on commercial prosthetic liner or custom made liner materials. We have characterized the load bearing capability of bubble actuator arrays at different actuation pressures. A limb-socket laboratory test setup was developed for capturing the internal pressure change of bubble actuators when the limb was subjected to the external force.
