This example of fully edible rechargeable battery, the first one ever made, would open the doors to new edible electronic applications.
“Future potential uses range from edible circuits and sensors that can monitor health conditions to the powering of sensors for monitoring food storage conditions. Moreover, given the level of safety of these batteries, they could be used in children toys, where there is a high risk of ingestion. Actually, we are already developing devices with greater capacity and reducing the overall size. These developments will be tested in future also for powering edible soft robots,” pointed out the research coordinator Mario Caironi.
“This edible battery is also very interesting for energy storage community. Building safer batteries, without usage of toxic materials, is a challenge we face as battery demand soars. While our edible batteries won’t power electric cars, they are a proof that batteries can be made from safer materials than current Li-ion batteries. We believe they will inspire other scientists to build safer batteries for truly sustainable future,” added Ivan Ilic, co-author of the study.
