Oxford researchers created a tiny, biodegradable lithium-ion battery from hydrogel droplets for various biomedical applications.
Animal model tests show the battery’s promise as a wireless, biodegradable solution for managing cardiac arrhythmias, a major mortality cause.Enlarged version of the droplet power source, for visualisation. 500 nL volume droplets were encapsulated in a flexible and compressible organogel.Researchers at the University of Oxford have developed a miniature, soft lithium-ion battery for biomedical applications like heart tissue defibrillation and pacing.
“To date, it is the smallest hydrogel lithium-ion battery and has a superior energy density,” said Dr Yujia Zhang , the lead researcher for the study and a starting Assistant Professor at the École Polytechnique Fédérale de Lausanne, in a statement.The development of tiny smart devices, often smaller than a few cubic millimeters, requires equally small power sources.
It has proven difficult to combine all of these features into a single battery, though. There is a big gap in the development of effective, secure, and adaptable energy solutions for biomedical applications because no power source currently in use can combine all these qualities at once.

Scientists develop method to control timing of synthetic DNA droplet divisionMany cellular functions in the human body are controlled by biological droplets called liquid-liquid phase separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside living cells but are not enclosed by membranes like most cell structures.
