NASA’s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology.  License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use.  NASA provides no funding in conjunction with these potential licenses.
NASA Langley Research Center has developed an infrasonic stethoscope that detects a broader range of physiological conditions than conventional stethoscope, use of which has declined mainly due to availability of other advance technologies such as the echocardiogram.  The echocardiograms can be complex, costly and require the need of a specialist for correct interpretation.  Further, it is estimated that more than 85% population of the world does not have access to advanced diagnostic tools such as echocardiogram and CT scans.  This scope provides additional data to physicians by monitoring signals across full frequency bandwidths that include cardiac, carotid artery, and respiration activities something that is not available in conventional stethoscopes.
Microphones and stethoscopes are regularly used by physicians to detect sounds when monitoring physiological conditions.  These monitors are coupled directly to a person's body and measure in certain bandwidths either by listening or by recording the signals.  The physiological processes such as respiration and cardiac activity are reflected in a different frequency bandwidth from 0.01 Hz to 500 Hz.  This technology can monitor physiological conditions in the entire bandwidth range.  Signals can also be wirelessly transmitted, using Bluetooth, to other recording devices at any other location.
To express interest in this opportunity, please submit a license application through NASA’s Automated Technology Licensing Application System (ATLAS) by visiting
If you have any questions, please contact Langley Research Center at with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information.  For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at
These responses are provided to members of NASA’s Technology Transfer Program for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities.  No follow-on procurement is expected to result from responses to this Notice.
