EVALUATING THE DYNAMIC PERFORMANCE OF INTERFACIAL PRESSURE SENSORS AT A SIMULATED BODY-DEVICE INTERFACE

BACKGROUND: Pressure sensing at the body-device interface can help assess quality of fit and function assistive devices during physical activities movement such as walking running. However, dynamic performance various pressure sensor configurations is not well established.
 OBJECTIVE(S): Two common commercially available thin-film sensors were tested to determine effects clinically relevant setup focusing on loading areas, interfacing elements (i.e. ‘puck’) calibration methods.
 METHODOLOGY: Testing was performed using a customized universal testing machine simulate dynamic, mobility loads interface. Sensor evaluated by analyzing accuracy hysteresis.
 FINDINGS: The results suggest that method has significant effect although difference mitigated an elastomeric puck. Both exhibited similar agree with hysteresis values reported manufacturers in previous studies assessing mainly static quasi-static conditions.
 CONCLUSION: These findings under conditions may be adequately represented via quasi-testing testing. This important since much easier apply reduces burden users verify prior clinical application. authors also recommend load puck for achieve optimal performance.
