Engineers from MIT have developed a special pill with a biodegradable antenna that wirelessly reports when it has been swallowed by the user. The antenna emits a signal within minutes of ingestion and then safely dissolves in the body. The technology is designed to work with existing drugs without the need to modify them. The system can help doctors monitor whether patients are taking their medications correctly, which is especially important for high-risk patients. Missing doses of medication can lead to serious health consequences that this technology could prevent. The smart pill represents an innovative approach to improving medication adherence and monitoring patient adherence.
