Project in collaboration with “Hôpitaux Universitaires de Genève”
The aim of this project is to create an innovative smart shoe, which will offload high plantar pressure and redistribute it dynamically on the sole in order to prevent foot ulcers and accelerate their healing. The offloading strategy is based on magneto-rheological (MR) pressure limiters. The insole will contain multiple MR modules with pressure sensors on top. An electronic board will be developed to acquire measurements of some tens of millivolts from the module’s pressure sensors simultaneously, as well as to supply the modules with sufficient energy, through battery power and gait energy harvesting. Through the development of the electronics and of a smart algorithm, the system will achieve plantar pressure redistribution, with low power consumption and high level of miniaturization. Unlike the existing cumbersome ulcer prevention solutions, the footwear will be comparable in size and aesthetics with standard footwear and will have an adequate battery lifetime, facilitating the everyday life of patients with diabetes.
