Electricity You Can Eat!

Edible electricity has been a topic of research for some years. There were some electronics that could do this. But if they degrade inside the body, that would create some problems.

Recently, some Engineers from Arizona State University have invented a powerful electronics from biodegradable materials that you can eat. It can power a camera and wipe out E.coli.

Foods like activated charcoal, gold leaf, Gatorade, seaweed, egg white, cheese, gelatin and barbecue sauce can store and conduct electricity. Sandwich them together, and you have a supercapacitor — a high-capacity electrical component that can store electrical energy temporarily. This tastes like cheese.

The invention cracks a number of problems. Implantable electronics require surgery. Biodegradable electronics exist, but they have low energy density and battery size is limited. Edible materials proposed in the past have toxic components that can cause stomach pain and nausea. This food may one day will help to treat cancer.

The devices were made by hand. In future they’ll be made by 3-D printers and will be much smaller than the “sandwiches” made by Jiang and his students, which are a little bit bigger than a soy sauce packet.
Here is the recipe!
