 Diabetic foot related issues such as extreme foot pain, plantar corns, and diabetic foot ulcers are common around the world. These issues can be assessed using a new in-shoe, low-cost, and multi-material pressure measuring insole, which is based on a piezo-resistive material. This device has a high number of sensors and was tested on 25 healthy volunteers and 25 patients, with varying degrees of diabetes. It was found that the device could measure plantar pressure from 5 kPa to 900 kPa, with an average hysteresis error of 3.25%. Plantar pressure increased from healthy to diabetic volunteers during both standing and walking, and the high-pressure contact area correlated strongly and positively with peak plantar pressure, R2 equals 0.78. During the heel strike phase, the diabetic volunteers had higher plantar pressure on their medial heels, while during the toe-off phase, the central forefoot was found to be a prevalent site for high plantar pressure among the diabetic volunteers.
