Bandage with biosensor

Smart bandage informs the smartphone about the wound healing process Svetlana Maslova, Hi-tech+

It is no longer necessary to constantly unwrap the wound to assess the healing progress. Traumatizing procedures will be replaced by wireless technology embedded in ordinary gauze.

The healing of chronic wounds — burns, blisters, deep cuts and ulcers — can be accelerated with a new smart bandage, according to a new paper published in Frontiers in Physics (Tessarolo et al., Wireless Textile Moisture Sensor for Wound Care). Thanks to a special technology, the doctor does not even have to examine the patient — special sensors assess the condition of the wound and its moisture level and send a notification to the smartphone when it's time to do the dressing.

Scientists sought to develop a simple, safe, disposable and inexpensive dressing for effective monitoring of skin repair. To do this, they used an organic semiconductor polymer (polystyrene sulfonate), which was applied to ordinary gauze. Changes in the moisture level of the wound cause corresponding changes in the electrical signal of the sensor and, under certain conditions, form a request for the need for dressing.

Preclinical experiments have shown that the technology has a very high sensitivity and can serve as a valuable tool in the treatment of wounds. Currently, scientists are developing dressings for various types of wounds to create optimal conditions for rapid healing.
