A new way to monitor vital signs using ingestible sensor that measures heart and breathing rates from within the digestive tract has been invented at MIT. In the near future, doctors will be able to use to monitor patients’ vital signs by having them swallow an ingestible electronic device that measures heart rate and breathing rate from within the gastrointestinal tract.
According to the report, this type of sensor could make it easier to assess trauma patients, monitor soldiers in battle, perform long-term evaluation of patients with chronic illnesses, or improve training for professional and amateur athletes, the researchers say.
The new sensor calculates heart and breathing rates from the distinctive sound waves produced by the beating of the heart and the inhalation and exhalation of the lungs.
“Through characterization of the acoustic wave, recorded from different parts of the GI tract, we found that we could measure both heart rate and respiratory rate with good accuracy,” says Giovanni Traverso, a research affiliate at MIT’s Koch Institute for Integrative Cancer Research, a gastroenterologist at Massachusetts General Hospital, and one of the lead authors of a paper describing the device in the Nov. 18 issue of the journal PLOS One.
The paper’s other lead author is Gregory Ciccarelli, an associate staff member at MIT’s Lincoln Laboratory. Senior authors are Robert Langer, the David H. Koch Institute Professor at MIT and a member of the Koch Institute, and Albert Swiston, a technical staff member at Lincoln Laboratory.
