A newly developed “smart pill” that can confirm whether a medication has actually been swallowed could one day change how doctors track prescription use. In a development aimed at improving medication adherence, engineers at MIT have created a pill that can confirm when it has been swallowed. The reporting mechanism can be built into standard pill capsules and includes a biodegradable radio frequency antenna. A tiny radio frequency chip then passes naturally through the digestive system and exits the body.
In this latest study, the researchers shifted their focus toward better tracking of medication use. They turned to radio frequency technology, which is safe for humans and easy to detect from outside the body. This allowed them to design a capsule that sends a signal once it has been swallowed, giving doctors a clearer picture of whether patients are taking their medicine.
