New Zealand researchers develop temperature-sensing tech for distant monitoring of diabetic sufferers’ toes

Researchers on the Auckland Bioengineering Institute within the College of Auckland have created a transportable know-how that senses temperature adjustments to detect toes issues amongst individuals with sort 2 diabetes.

The analysis staff, led by Suranga Nanayakkara, an affiliate professor on the college, lately acquired funding underneath the Analysis Activation Grant of the federal government’s Well being Analysis Council to check out the “low-cost” machine on sufferers at a podiatry clinic in Auckland. 


Based mostly on the college’s press assertion, FootSense is supposed for home-based monitoring to identify early indicators of foot issues. It measures irregularities in temperature, which in keeping with analysis, might point out compromises in blood stream, resulting in foot ulcers or worst, the necessity for amputation.

The machine was initially developed by Dr Samitha Elvitigala when he was nonetheless an undergraduate scholar in Sri Lanka. Its earlier iteration was improved to scan and map temperature variations through a platform the place sufferers can stand.


It’s “essential” for folks with sort 2 diabetes to endure common foot checking, the ABI harassed. In 2020, about 8% of the adults in New Zealand had been affected by the illness. Information from the New Zealand Medical Journal and the Ministry of Well being exhibits that Māori persons are 65% extra more likely to endure main amputation.

The machine was created in order that sufferers, particularly these prone to or affected by foot issues, will not should exit and journey extra for getting their toes checked.


Within the US, there are foot units that monitor indicators of diabetic foot ulcers. Notable merchandise are the sensible sock by Siren and Podimetrics’ SmartMat. The latter was deployed in a research final 12 months that confirmed day by day foot temperature monitoring may end up in decrease charges of hospitalisation and foot ulcer recurrence in high-risk sufferers. 

In different information, Dr Elvitigala created a number of applied sciences for the toes for his lately defended doctoral thesis. One is GymSoles, a sensible insole that renders real-time suggestions on the supply of stress to assist customers do right workout routines, equivalent to squats and weightlifting. One other invention is StressFoot, which was designed to detect stress through foot stress and movement.


“Sufferers who come to the clinic will get their toes scanned, and we are able to use that information to enhance the efficacy of the machine. The following step could be fascinated by how we are able to make them out there – the way to manufacture them in an inexpensive method,” Dr Elvitigala stated.

“We hope in the long term our StressFootSense machine will enhance well being fairness in New Zealand by permitting for at-home monitoring that can, in flip, permit for early intervention [a]nd keep away from the necessity the hospitalisation and surgical procedure,” he added.
