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 102016-92017, 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 hardwaresoftware 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.
