MIT scientists create hydrogel smart wound dressing

Cambridge, Massachusetts — Researchers from the Massachusetts Institute of Technology (MIT) released a new hydrogel last month; a water-based, flexible, smart wound dressing that is capable of holding small electronics to read skin temperature and automatically deliver the drugs required by patients.

“Electronics are usually hard and dry, but the human body is soft and wet. These two systems have drastically different properties. If you want to put electronics in close contact with the human body for applications such as health care monitoring and drug delivery, it is highly desirable to make the electronic devices soft and stretchable to fit the environment of the human body. That’s the motivation for stretchable hydrogel electronics,” said Xuanhe Zhao, associate professor from the Department of Mechanical Engineering of the MIT.
