Overview

• 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.
