The miTag monitors a patient’s location, heart rate, and oxygen saturation and relay this information over a wireless ad-hoc mesh network to monitor stations. Thousands of patients can be monitored simultaneously over the miTags' resilient wireless network. miTags can facilitate the tasks of patient monitoring and tracking, documentation, and coordination currently undertaken by the medical care providers.

When using medical sensors within a wide variety of health care applications, designing a device that can deliver the suitable functionality that tailors to patient, provider, and workflow needs can be a critical challenge. The miTag is a reconfigurable platform that allows easy expansion to additional sensors and dynamically tunes its functionality to be patient-centric and workflow-specific.

miTags are different from conventional wireless patient monitors because their technology innovations enable three key benefits for the healthcare community: they are user-centered, cost-effective, and convenient for ad-hoc deployment. They combine innovations in smart dust hardware, reconfigurable software and ad-hoc mesh networking, which all contribute to make miTags applicable to numerous patient monitoring applications. One compelling application is the monitoring and tracking of casualties at a disaster scene. Recent events in global terrorism, military conflicts, and natural disasters are raising international concern on our nation's overcrowded hospitals and their ability to provide adequate emergency medical care. For years, medical providers have been conducting rounds of patient care by manually measuring vital signs and documenting assessments on paper. The Department of Homeland Security mass casualty drill showed that miTags can increase the patient care capacity of responders in the field. miTags are deployed at multiple hospitals across the US.
