Infrascope: Full-Spectrum Phonocardiography with Automated Signal Analysis
Completed
TRL 2 (started at 1, targeting 2)
Description
Langley Research Center (LaRC) has developed a low frequency acoustic sensor capable of sensing frequencies below the human range of hearing primarily for aeronautical applications. The Kennedy Space Center (KSC) Biomedical Engineering and Research Lab is partnering with LaRC to explore medical applications of this device initially as a low frequency stethoscope. We will compare the output of the Infrascope to more traditional methods like EKG signals and Real-Time Blood Pressure to try and draw basic correlations and begin to interpret the output of the Infrascope. Using digital signal analysis tools, we will generate a repeatable output from the infrascope and compare it to the output of a traditional electrocardiogram, and real time blood pressure. We will compare the signals to determine what known information is present in the output of the infrascope, what possible additional information may be present, and attempt to automate the analysis of the Infrascope signal.
Benefits
This technology may improve the accuracy and objectivity of traditional phonocardiography and may broaden the scope of the information available through phonocardiography. It may form the basis for improved, low-cost, noninvasive medical tests. In addition to cardiac monitoring, the Infrascope could be used in biometrics applications, where the wave form generated could possibly be used to identify personnel.

How to get involved
This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
