Diabot: Development of a Diabetic Foot Pressure Tracking Device

Foot-related problems are prevalent across the globe, and this issue is aggravated by presence of diabetes mellitus. Diabetic-foot-related issues include extreme foot pain, plantar corns, diabetic ulcers. To assess these conditions, accurate characterization pressure required. In work, an in-shoe, low-cost, multi-material measuring insole, based on a piezoresistive material, was developed. The device has high number sensors, tested 25 healthy volunteers patients with different degrees diabetes. working range observed to be 5 kPa 900 kPa, average hysteresis error 3.25%. Plantar found increase from volunteers, in terms both standing walking. case group, the-high contact area strongly positively correlate (R2 = 0.78) peak pressure. During heel strike phase, showed medial region. regard toe-off central forefoot site for volunteers. developed expected not only assist prediction ulceration or re-ulceration, but also provide strategies suggestions alleviation pain mitigation.
