Lincoln Laboratory’s Ingestible Physiological Status Monitoring (PSM) Device

Dept. of Defense

Laboratory: Massachusetts Institute of Technology (MIT) Lincoln Laboratory

Technology: Ingestible Physiological Status Monitoring (PSM) Device (The “PSM” Pill)

Opportunity: This patent-pending technology is available for licensing.

Details: Physiological status monitoring (PSM) systems can provide data for necessary preventative interventions, improved performance, risk mitigation, or monitoring illness or after injury. Current PSM devices are less than ideal due to a number of limitations, including limited battery life, poor signal fidelity, and general ergonomic obtrusiveness. This invention is an ingestible, minimally intrusive PSM device that measures heart rate, breathing rate, and core temperature for reliable and rapid monitoring of physiological status.


  • Inexpensive
  • Extended battery life with optional recharging capabilities
  • Operational anywhere in the GI tract and can be transient or persistent
  • Improved patient comfort
  • Measures true core temperature, which isn’t currently obtainable except with rectal thermometry

Applications: This invention provides real-time internal monitoring of vital signs with improved accuracy over external measurements, useful for field assessment of patients or home monitoring and management of chronic illnesses. This device may also be used for operational safety monitoring for military personnel or first responders, or to improve performance and safety for athletes. This device can detect a number of medical conditions, including, sepsis, arrhythmias, aortic stenosis, hypertrophy, asthma, and chronic obstructive pulmonary disease (COPD) exacerbations.
