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 this project period (10/2016-9/2017), the sensor development effort has been focused on 1) implementing a test apparatus for calibration and testing of the antenna sensors in a condition imitating limb-socket interaction; 2) instrumenting a socket that can be worn by able-bodied volunteer to facilitate data collection and sensor calibration during walking; 3) establishing a procedure to design and calibrate the antenna shear and pressure sensor; 4) explore textile materials to produce robust antenna sensor that can be embedded in prosthetic liners; 5) investigating wireless interrogation of the antenna sensor without a connector; and 6) studying microstrip resonators for bioimpedance measurement. For actuation, we have 1) improved and de-bugged the prosthetic interface control hardware/software and tested the data acquisition system to improve the precision of the recorded and displayed pressure value within each gait cycle; 2) designed and built a working miniaturized control unit that reduced the weight by 63.5% (3.08 lb compared to the previous version of 4.85 lb) in weight and the volume by 56% (6x6x5 compared to 10x8x4 in the previous version).
