Edible furniture can supply important energy in emergencies. Our digestive system is crucial and requires regular examination – whether it’s by ultrasound, colonoscopy, or a mini camera that can be swallowed.
Now, an Italian research team has developed an edible prototype to replace the metal batteries used in these devices.
Acting as anode and cathode respectively, Vitamin B2 and quercetin were embedded in activated charcoal to increase conductivity and applied to electrodes made from edible gold foil.
Nori seaweed was placed in between to prevent short-circuiting. The 0.65 volt battery, encapsulated in beeswax, can be swallowed without harm.
With a current of 10 microamps per hour, it can already (briefly) power an LED light.
Now, how about an arrabiata boost?
