MiWa Technologies has developed the Cardiopulmonary Stethoscope, a low-cost, non-invasive integrated radio frequency-based system for lung water and vital sign measurements.


Being able to closely monitor the changes in lung water, respiratory rate, and heart rate, are the foundation for proactively preventing worsening of patients’ heart failure.


  • 5.1 million people in the United States have Heart Failure, 23 million worldwide

  • 550,000 new patients every year in the U.S.

  • Heart Failure costs $39 billion annually in the U.S.

A new tool for the early detection of heart failure 

National Science Foundation June 2014

Until recently, a reliable, low-cost, non-invasive method to measure changes that occur in the water content of the lungs did not exist. Yet, having such a device could be an important tool for the early detection of heart failure, which afflicts an estimated 5.1 million Americans and is a leading cause of hospitalization and death.

Microwave Stethoscope Lets Physicians Peer Into the Lungs   

IEEE Spectrum Oct. 2014

"...a team of researchers at the University of Hawaii, at Manoa, have a new way to measure lung water, along with many other vital signs. As their coin-size sensor rests on a patient’s chest, it emits microwaves and measures how they reflect. The list of what the researchers can decode from these patterns of reflected microwaves is only growing."
