Paper Abstract

A light-weight, soft, robust and low cost sensory system integrated into the inner soles of footwear is being developed that channels information to a mobile device, allowing to assess the ergonomics of the technique applied and to achieve improved performance in several fields of sport, to develop orthopedic footwear or monitor elevated plantar pressures for several fields of medicine, including early detection of diabetic foot ulceration. The advantages and disadvantages of several sensory material types were considered in the present work, focusing on signal reproducibility for periodic pressure measurements, response frequency and long-term stability, especially after extended load periods. Promising results were obtained for both capacitive and resistive sensory materials, utilizing virtually the same electronics platform for both types.
