Diabetic ulcers, which occur in patients with diabetes, are dangerous complications that can lead to amputation if the treatment window is missed.

How the smart wound patch works

The patch combines an optoelectronic sensor, which can simultaneously measure multiple types of biological information, with a functional dressing. It can analyze glucose concentration, acidity (pH, an indicator of hydrogen ion concentration), and temperature changes at the wound site in real time, and patients can check their condition themselves using a smartphone.

The research was published in Advanced Functional Materials.
