Researchers have developed a miniature soft lithium-ion battery that could be used as a defibrillator to control heart rhythm during surgery. The flexible lithium-ion battery is constructed by assembling biocompatible hydrogel droplets. The state-of-the-art device is the smallest soft lithium-ion battery with the highest energy density. The research opens the way to developing tiny bio-integrated devices, with a range of applications in robotics, biology, and medicine.
