Non-invasive Low-cost Cardiovascular Activity Monitoring
We harness the power of technology to revolutionize the way we monitor heart function and diagnose cardiovascular diseases. By measuring the vibrations generated by cardiac activities such as valve opening and closure, we are able to noninvasively gather critical diagnostic information. Our expertise in computational models, signal processing, and machine learning allows us to accurately characterize these signals, leading to the development of innovative cost-effective methods for monitoring and diagnosis of cardiovascular diseases. With a focus on precision and accuracy, our work has the potential to improve patient outcomes and change the future of healthcare, particularly within low-income populations and underserved areas.

Cardiovascular disease is a leading cause of death globally, highlighting the need for effective diagnostic tools for early detection and intervention. Seismocardiography (SCG) is a noninvasive method for evaluating cardiac activity, however, the complexity of SCG signals presents challenges in its application. Recent advances in low-cost sensors, signal processing, and machine learning have led to renewed interest in SCG and its potential utility. This review examines the recent progress in the field of SCG.
In the past few decades, many non-invasive monitoring methods have been developed based on body acoustics to investigate a wide range of medical conditions, including cardiovascular diseases, respiratory problems, nervous system disorders, and gastrointestinal tract diseases. Recent advances in sensing technologies and computational resources have given a further boost to the interest in the development of acoustic-based diagnostic solutions... Read more!
