Scientists have developed an ingestible battery that can power medical devices inside pigs for up to three days, in a milestone towards potential human use for health monitoring and treatments.
The paper-based battery, which was safely broken down in the animals’ bodies, could help with important tasks in the digestive system including drug release and the regulation of appetite-related signals, researchers said.
The development is part of a wider effort to deploy innovations such as tiny robots in the human body to improve the effectiveness of therapies and avoid the need for surgery.
“This moves the technology beyond a materials demonstration toward an integrated biomedical system,” said Giovanni Traverso, research leader and an engineering professor at the Massachusetts Institute of Technology.
