Electric Eel-Inspired 'Jelly Batteries' Pave Way for Wearable Tech and Medical Implants

Cambridge researchers develop stretchable, conductive batteries that mimic human tissue, offering potential for soft robotics and brain implants.

Scientists created 'jelly batteries' inspired by electric eels' electrocytes, combining stretchability and conductivity.
The batteries are made from hydrogels, which are 3D polymer networks containing over 60% water.
These batteries can stretch up to 10 times their original length without losing conductivity.
Potential applications include wearable devices, soft robotics, and biomedical implants for drug delivery and epilepsy treatment.
The research team plans further testing in living organisms to explore medical applications.
