L’Italian Institute of Technology (IIT) developed the first prototype of edible rechargeable batteryinserted by the magazine Time between 200 best inventions of 2023. The advantage of an invention of this type is that it is completely biocompatible, that is, it has no negative effects on our body. Applications range from medical devices for delivering drugs within the body to powering portable devices.
The first prototype of the battery was created by the group of Mario Caironicoordinator of Printed and Molecular Electronics Laboratory at the IIT a Center Milanusing molecules present in foods such as almonds, capers And algae. Following the creation of the prototype, a study was published in the journal by Caironi’s group Advanced Materials.
How the battery was made the first edible battery
An essential element in the construction of a battery are the two poles, called the anode (positive pole) and the cathode (negative pole). In this battery the anode was made using the riboflavin (or vitamin B2), present for example in almondswhile the cathode with della quercetin present for example in capers.
From the nori seaweed (also used for the preparation of sushi) were then used as separators to avoid short circuits. The electrolyte of the prototype is water-based.
Thanks to this composition, the battery would not create problems for the human body even if ingested 0.65V allows the device to work at a sufficiently low voltage from not be harmful for man.
The battery developed by the group of Caironi can provide a current of 48 μA (microampère) for approx 12 minutes and is able to power, for example, LEDs at low power.
Caironi regarding the inclusion of your group’s work in the list of Time he has declared:
In research, especially when traveling along little-traveled paths, it is not a given that on the one hand you obtain results and on the other that these are noticed so quickly. This motivates us even more to continue. Huge credit goes to Ivan Ilic, a former team member, who led the creation of the battery.
