Oxford creates world’s smallest biodegradable battery for medical use
Oxford researchers created a tiny, biodegradable lithium-ion battery from hydrogel droplets for various biomedical applications.
“To date, it is the smallest hydrogel lithium-ion battery and has a superior energy density,” said Dr Yujia Zhang (Department of Chemistry, University of Oxford), the lead researcher for the study and a starting Assistant Professor at the École Polytechnique Fédérale de Lausanne, in a statement. According to the team, proof-of-concept heart treatments conducted in animal models demonstrated its potential as a promising wireless and biodegradable solution for managing cardiac arrhythmias, which are a leading cause of mortality worldwide. “The tiny soft lithium-ion battery is the most sophisticated in a series of microscale power packs developed by Dr Zhang and points to a fantastic future for biocompatible electronic devices that can operate under physiological conditions,” said Professor Hagan Bayley (Department of Chemistry), the research group leader for the study, in a statement.
