Researchers from the University of South Wales (USW) in the UK are set to develop biodegradable batteries that can be positioned in the body of humans for powering medical implants.
The batteries are designed to be stretchable and ultra-thin, allowing them to move naturally with the body’s movements.
They are also biocompatible, ensuring that the materials used are non-toxic.
Unlike conventional batteries that use lithium, these batteries are said to utilise chemicals such as calcium and sodium, which do not pose a risk to human health.
After their charge has been used up, the batteries will dissolve safely within the body, eliminating the need for surgical removal.
The research is led by Dr Hammad Nazir from USW鈥檚 Smart Energy Storage Solutions research group.

By GlobalDataHe and his team members, Darren Haines and Abdullah Hakimuddin, are currently exploring the behaviour of battery materials in biological environments. Their focus is on assessing the materials’ biodegradability and biocompatibility.
Dr Nazir noted that the team has detected several design concepts like hydrogel-based and zinc-saltwater systems, which provide theoretical benefits in terms of flexibility, natural degradation, and safety.
Human trials for these biodegradable batteries are not yet in progress, and the team’s priority is to thoroughly research the mechanical properties, materials, and safety profiles of any potential designs.
Dr Nazir said: 鈥淢odern medical wearables – from heart monitors to insulin regulators – are advancing rapidly, but the power sources they rely on remain outdated – they are bulky, rigid, and not always safe for the human body. The research team is changing that narrative.
鈥淧re-clinical evaluations, including lab-based biocompatibility testing and device prototyping, will inform the next steps before any clinical pathway is considered. This isn鈥檛 just innovation for the lab – it鈥檚 real impact for future patients. Imagine a world where a heart implant powers itself safely, or a wearable health sensor biodegrades once its job is done.鈥�
