Abstract:

Chronic wounds or ulcers are wounds that do not cure in the usual manner. This type of wound is most common in the old age group and in paralysis patients with an estimated 1% of the population suffering from leg ulcers. There is need to develop a device capable of remote wound monitoring that enables patients to take charge of their wound management under clinical guidance. A new wound mapping device has been developed, which is based on electrical impedance spectroscopy and involves the multi frequency characterization of the electrical properties of wound tissue under an electrode array. The main feature of the prototype device is the expected facility of the measuring array into standard commercial closed dressings and thereby protecting the wound from interference and contamination. Hence promoting wound healing, while monitoring the protected wound. Foot ulcers account for increasing risk associated with diabetes. No device continuously monitors the status of foot ulcers when patients are not hospitalized. A temperature sensor and a pH sensor are capable of monitoring diabetic foot. With the variations in the electrical resistance of a nanocomposite consisting of multiwalled carbon nanotubes and poly (styrene-b- (ethylene-co-butylene) -b- styrene) temperature is measured. The pH sensor used here is a graphene oxide (GO) layer that changes its electrical potential when the pH changes. The temperature sensor has a sensitivity of ~85 Ω/°C in the range 25°C–50°C and a high repeatability. Thus with the utility of these sensors it is highly possible for early detection of chronic ulcers.
