Scientists of the Italian Institute of Technology have carried out an important study in the field of molecular electronics. They have produced an “edible battery” that operates at 0.65 volts and provides 48 microamps of current for 12 minutes, albeit with a low capacity compared to commonly used batteries.
Moreover, these batteries contain materials produced from starch and sugar obtained from foods such as corn, sugar beet and potatoes. While the anode, that is, the positive end of the battery, consists of riboflavin, that is, vitamin B2; The negative, that is, the cathode tip, consists of quercetin, that is, vegetable components that also contain vitamin C.
So where will these edible batteries be used?
The most important area of use is health. Within the scope of the research, it was aimed to meet the energy needs of the devices attached to our body and inserted into the blood circulation for the purpose of health monitoring and control of these batteries. Batteries are designed in such a way that they can be digested by the stomach like a food and thrown out of the body when they are finished. However, for this, not only the batteries, but also the related sensors must be produced in edible form. Another area of use is toys used by children. However, for this, it is necessary to produce larger batteries with larger capacities.
The battery, not the white chocolate bar:
Other materials inside the battery are more remarkable. Activated charcoal, which is used to treat food poisoning, is used to conduct electricity in batteries. In addition, “edible gold”, which is indispensable for luxury restaurants, is used at the ends that will connect the batteries to the device.
