A new kind of heat-absorbing heat-sensing film, which can be placed inside a vacuum, has been invented by researchers from the University of Illinois at Urbana-Champaign.
The film is flexible and can be inserted into the body to block incoming heat from entering the body.
The researchers say that it can also be used to capture heat generated by the body’s internal mechanisms, such as the heart, brain, kidneys and sweat glands.
“There is still a lot of work that needs to be done in this area to better understand this process,” said senior author Alex T. Shafir, a professor of materials science and engineering at the university.
“What’s really exciting about this is that we’re just at the beginning of a big scientific adventure.
I think the potential is tremendous.”
The new film is based on a thin film of graphene, which is a semiconductor made up of two layers of carbon atoms sandwiched between a layer of aluminum oxide.
Researchers say it is extremely strong and flexible.
It’s not clear how it would work in the body, but it would be used for sensing external forces such as heat and cold, as well as internal temperature.
To make the film, the researchers used graphene as a material for making graphene electrodes, which are electrodes made of a similar material to graphene.
These electrodes are connected to an array of electrodes that are placed inside the body and act as heat-absorbent insulators.
The insulators allow heat to escape.
“The film could be applied to a variety of body functions, including internal and external heat sources, and is an excellent candidate for heat-resisting medical devices,” said Shafar.
To conduct the study, Shafriars group fabricated and tested the film and made the electrodes.
“In our experiments, the film produced a heat-based image in the skin that could be used as a thermal-resistance indicator,” Shafari said.
Shafir said the next step in the research is to develop more efficient heat-resistant materials.
“Ultimately, this is an exciting technology for the biomedical industry,” he said.
The researchers said they would like to use the technology to develop a sensor that can measure temperature and temperature-related signals inside the human body.
