Patent ID: 10721993

Abstract:
A plantar surface pressure offloading system includes an insole capable of coupling with a shoe and interfacing with a foot. A number of compressible bladders and pressure sensors are coupled to the insole. Each bladder has an adjustable compressibility, and each pressure sensor is configured to measure a pressure exerted on a respective portion of the foot. A controller of the system can perform, for each compressible bladder, a compressibility adjustment process including (i) receiving, from a respective pressure sensor associated with a respective bladder, a signal indicative of a pressure exerted on a respective portion of the foot, (ii) determining, based on the signal, that the pressure exerted on the respective portion of the foot exceeds a threshold pressure, and (iii) responsive to the determination, adjusting the compressibility of the respective bladder, thereby offloading pressure from the respective portion of the foot to a different portion of the foot.
