A breakthrough new design utilizing microgels can help heal wounds exacerbated by suppressed immune systems.
, but a remarkable new device could soon offer a much more effective and cost-efficient way to not only help patients heal, but do so better than ever before.Researchers at Stanford University have designed a smart bandage capable of monitoring wounds’ healing in real time, as well as accelerate tissue growth and blood flow around them while reducing scar severity.
Photographs of the smart bandage showing the microcontroller unit , crystal oscillator, high-pass filter , stimulation and sensing electrodes, flexibility of the printed circuit board, adhesion of the hydrogel interface to skin, and thin layout of the board.“In sealing the wound, the smart bandage protects it as it heals,” the research paper’s first co-author, Yuanwen Jiang, explained
. “But it is not a passive tool. It is an active healing device that could transform the standard of care in the treatment of chronic wounds.”Electrical stimulation, also known as galvanotaxis, has been shown to accelerate a multitude of wound healing processes, although researchers note there is much to still learn regarding its influences—something the smart bandage’s eventual deployment could also help accomplish.
