Researchers have developed a laser-induced graphene sensor material that when embedded into a bandage could enable improved tracking of healing wounds.
Wearable sensors have many applications, one of which is to remotely monitor a patient’s wound while it heals.
The challenge, however, is that these sensors are not able to distinguish different signals when they occur at the same time – for instance, between temperature and physical strain.
Researchers from Penn State University and China’s Hebei University of Technology have addressed this issue by developing a new type of flexible sensor material using graphene that can accurately measure different signals, such as temperature and physical strain, simultaneously.
Huanyu ‘Larry’ Cheng of the department of materials science and engineering at Penn State said: “By accurately measuring both temperature changes and physical deformation or strain created by a healing wound, it could revolutionise the tracking of wound healing.
“Doctors could...
