Chronic wounds like diabetic skin ulcers require continuous monitoring to ensure they don’t worsen, and a new bandage using graphene is being developed that could make it easier for physicians to keep track of such injuries.
Grapheal, which spun out of France’s National Centre for Scientific Research, is leading the development of the device, consisting of a polymer film base and embedded flexible electronics, including graphene electrodes, which make direct contact with the wound being monitored, according to New Atlas.
Data collected by the electrodes is transmitted wirelessly to a mobile device, and then to a cloud-based server for a medical professional to view. This data can include chemical changes to the composition of the wound, such as fluctuating pH indicating a healing or worsening infection, promptly alerting the caregiver and patient to the change.
The bandage could have major implications on the future of telehealth, where patients are less often required to see a doctor in person. Human trials are on pace to begin soon, and the bandage is anticipated to become commercially available within the next 3 years.
