Researchers are developing a novel wearable ultrasound device poised to dramatically expand the scope of heart monitoring, offering continuous assessment beyond traditional clinical settings. The technology, a collaboration between Singapore-MIT Alliance for Research and Technology, MIT, and several Singaporean universities, aims to capture detailed cardiovascular data throughout a patient’s daily life-a significant step towards proactive and personalized healthcare [[1]]. Initial clinical trials are planned at Tan Tock Seng Hospital, with the promise of earlier diagnoses and reduced strain on hospital resources.
A new wearable ultrasound device is in development that could revolutionize heart monitoring, moving the technology beyond the hospital and into patients’ everyday lives. Currently, ultrasound examinations are typically conducted in clinical settings, but researchers are working to create a small, wearable system capable of continuously observing heart function for extended periods.
The device aims to capture fluctuations in blood pressure and heart performance throughout the day, influenced by factors like activity, stress, and sleep – data traditionally difficult to obtain outside of a controlled medical environment. By tracking these changes over time, clinicians may be able to identify subtle warning signs and patterns that would be missed during infrequent office visits. This shift in monitoring could also alleviate pressure on busy hospitals and free up specialized personnel.
The project is a collaborative effort led by the Singapore-MIT Alliance for Research and Technology, with participation from the Massachusetts Institute of Technology (MIT), Nanyang Technological University, and the National University of Singapore. Clinical trials are slated to take place at Tan Tock Seng Hospital.
Why New Materials are Key to Making Ultrasound Practical for Daily Use

The innovation isn’t necessarily in the ultrasound technology itself, but rather in how it’s delivered. Traditional ultrasound requires gels, rigid probes, and a stationary patient – conditions not conducive to real-world use. The new system utilizes bioadhesive materials that gently adhere to the skin and conform to the body’s movements. These materials are designed to be non-irritating, sweat-resistant, and capable of maintaining contact for hours.
Advanced manufacturing techniques, including 3D printing, are crucial to the device’s development. These printers create structures at the submicrometer level, allowing for extremely fine surfaces that adapt to the contours of the skin and underlying tissues. This precise contact ensures a stable image, consistent quality, and reliable measurements even during activities like walking or sleeping.
Long-Term Data May Reveal Heart Problems Missed by Short Tests
For individuals with conditions like hypertension or heart failure, understanding trends over time is often more valuable than a single measurement. Does blood pressure spike at night? Does heart function decline with exertion? Do anomalies occur sporadically? A wearable ultrasound device could reveal these patterns, providing physicians with a more comprehensive view of a patient’s cardiovascular health. The ability to track changes over extended periods could lead to earlier and more accurate diagnoses.
The volume of data generated by the device would be overwhelming for manual review. Therefore, the images will be analyzed using artificial intelligence (AI) systems. Algorithms will compare trends, identify deviations, and highlight areas of concern, serving as a tool to assist – not replace – clinical judgment.
Clinical Studies Will Evaluate Real-World Performance
The system is still under development, and initial studies will focus on assessing the reliability of long-term measurements in everyday settings. Researchers will evaluate image quality, comfort, and stability over extended wear times. The first clinical tests will involve heart patients, where detecting subtle changes is particularly critical.
The team is also working on refining other components, including new ultrasound transducers, customized microelectronics, and materials that provide an even better fit. The goal is to create a fully integrated platform ready for widespread use within three years.
Bridging the Gap Between Smartwatches and Clinical Systems: A New Category of Device
This multi-year project is supported by several million euros in funding and is expected to have broader implications for both industry and the job market. The development of new manufacturing techniques, sensor technology, and data analysis methods will create demand for specialized expertise. Medical device manufacturers are also closely monitoring the progress.
Ultimately, wearable ultrasound has the potential to establish a new category of medical devices – positioned between consumer smartwatches and traditional clinical systems. Unlike fitness trackers that provide approximate data, this technology delivers detailed imaging data from within the body, representing a significant advancement in diagnostic capabilities.
In Brief:
- A wearable ultrasound device allows for continuous heart monitoring, capturing data beyond the confines of a hospital visit. This provides doctors with insights into what happens between appointments.
- Instead of isolated measurements, the device generates longitudinal data, particularly useful for managing conditions like hypertension or heart failure. AI assists in identifying anomalies without replacing physician expertise.
- The technology aims to reduce the burden on hospitals and improve patient care by enabling remote monitoring. This frees up healthcare professionals and provides patients with earlier, more precise information.
