Scientists have successfully etched edible circuits on the surface of food, paving the way for RFID-labeled food products that can help us track farm food in the womb. The project, which uses something called laser-induced graphene (LIG), is a process that creates a “foam made of tiny reticulated graphene flakes” that can carry electricity through carbon-rich products like bread , potatoes and cardboard.
“Overall, the process has demonstrated that LIG can be burned into paper, cardboard, cloth, charcoal, potatoes, coconut, toast and other foods,” wrote the researchers. Smalley-Curl Institute and Ben Gurion. University of the Negev.
The method may incorporate or etch patterns that could be used as supercapacities, radio frequency identification (RFID) antennas, or biological sensors. Based on these results, the researchers theorized that any substance with a reasonable amount of carbon can be transformed into graphene. To test this theory, the Tour team sought to burn LIG in food, cardboard and several other carbon-based materials every day.
You probably will not impose energy sources and other components on your Pop Tarts, but this early research into edible circuits could pave the way for a smarter diet.
