The patch developed by the research team 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.
In other words, if the wound condition worsens, the dressing color changes, allowing danger signals to be easily checked with the naked eye.
Through this, abnormal signs that could lead to tissue necrosis can be detected and tracked over long periods in a non-invasive manner, meaning without cutting the skin or drawing blood.
This provides more accurate and stable data than ordinary camera-based imaging because it is less affected by changes in surrounding lighting.
