A high-tech bath mat takes just 20 seconds to spot dangerous foot ulcers* weeks before they start to show.

The device has temperature sensors that detect “hot spots” on the soles of feet, which indicate an ulcer may develop in a few days or weeks.

These invisible* hot spots are caused by inflammation under the skin that develops when blood circulation is reduced and skin is deprived of the vital oxygen it needs — increasing the risk of ulcers that do not heal.

Patients stand on the mat at home for 20 seconds a day. If the mat detects no change in skin temperature then a green light flashes. The temperature data is then automatically transmitted through a wireless connection to a patient’s doctor.

If the mat senses a significant increase, even in one tiny spot, it flashes red.

The device may help diabetics at risk of foot amputation* as circulation to the lower limbs is damaged by their illness.(SD-Agencies)
