An ingestible capsule that can track vital signs, including heart rate and breathing patterns, from inside a patient’s digestive system was created by Massachusetts Institute of Technology researchers. The innovative gadget, according to the experts, may also identify respiratory depression symptoms that accompany an opioid overdose. The gadget will be particularly helpful for sleep studies, according to Giovanni Traverso, an associate professor of mechanical engineering at MIT who has been working on creating a variety of ingestible sensors.

Patients in sleep studies typically need to be connected to multiple sensors and devices. Sensors can be wired to a patient’s scalp, temples, chest and lungs in lab settings or at-home research investigations. A patient may also be asked to wear a chest belt, nasal cannula and pulse oximeter that connects to a portable monitor. It’s difficult to try to sleep with all this equipment.
