You can have your toast and play it too, sort of. Scientists are working on printing edible electronics, and they’re using toast to test their theory.
|Graphene on toast could lead to edible electronics|
Scientists who introduced laser-induced graphene (LIG) enhanced their technique to produce what may become a new class of edible electronics.
The chemists, who once turned Girl Scout cookies into graphene, are investigating ways to write graphene patterns onto food and other materials to quickly embed conductive identification tags and sensors into the products themselves.
“This is not ink. This is taking the material itself and converting it into graphene.”
“This is not ink,” says James Tour, chair of chemistry and professor of computer science and of materials science and nanoengineering at Rice University. “This is taking the material itself and converting it into graphene.”
The process is an extension of the idea that anything with the proper carbon content can be turned into graphene. In recent years, the lab developed and expanded upon its method to make graphene foam by using a commercial laser to transform the top layer of an inexpensive polymer film.
The foam consists of microscopic, cross-linked flakes of graphene, the two-dimensional form of carbon. LIG can be written into target materials in patterns and used as a supercapacitor, an electrocatalyst for fuel cells, radio-frequency identification (RFID) antennas, and biological sensors, among other potential applications.
