The objective of PASSO is the development of a complete system that can guarantee a fully conformable sensing and correction of non-physiological foot weight distribution for the prevention of ulcers in diabetic patients. A smart active insole, through a biometric sensing layer, will detect the physical parameters in terms of local pressure and temperature, underlining a non-physiological weight distribution. The device will then be able to directly correct the posture by an active layer composed of multiple air cavities which can be inflated or deflated, changing the local conformation and thus the local pressure and related temperature.
