The Wearable Imaging for Transforming Elderly Care (WITEC) research group has launched an innovative project aimed at developing the world’s first wearable ultrasound imaging system. This cutting-edge technology is designed to continuously monitor chronic health conditions in real time, empowering healthcare providers with earlier insights, faster diagnosis, and more timely interventions.
By enabling non-invasive, continuous imaging outside traditional clinical settings, the initiative has the potential to significantly improve quality of care and long-term health outcomes for the aging population.
What If Ultrasound Imaging Was No Longer Limited to Hospitals?
Imagine a future where ultrasound imaging is no longer restricted to hospital rooms or specialist clinics. Instead of relying on occasional scans or infrequent check-ups, patients living with chronic conditions such as hypertension and heart failure could be monitored continuously—at home, in the community, or even while on the move.
This shift would fundamentally transform health care delivery. Rather than reactive, hospital-centric treatment triggered only after symptoms worsen, clinicians could gain continuous, real-time clinical insights, enabling earlier detection, faster intervention, and truly personalized care. Preventive, community-based health care could replace episodic snapshots with a complete and dynamic picture of a patient’s cardiovascular health.
Turning Vision Into Reality: The Launch of WITEC
To bring this vision to life, the Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore, has launched a groundbreaking collaborative initiative known as Wearable Imaging for Transforming Elderly Care (WITEC).
WITEC represents a major leap forward at the intersection of wearable technology, medical imaging, materials science, artificial intelligence, and clinical research. Its mission is ambitious: to develop the world’s first wearable ultrasound imaging system capable of up to 48 hours of intermittent cardiovascular imaging, enabling continuous and real-time monitoring of chronic diseases such as hypertension and heart failure.
A Pioneering Multi-Institutional Research Effort
This multi-million-dollar, multi-year research program is supported by the National Research Foundation Singapore under the Campus for Research Excellence and Technological Enterprise (CREATE) program. It brings together world-class expertise from Massachusetts Institute of Technology, Nanyang Technological University, and National University of Singapore.
Clinical validation is led by Tan Tock Seng Hospital, which will conduct patient trials to assess the feasibility and effectiveness of long-term heart imaging for chronic cardiovascular disease management in real-world settings.
Redefining Health Care Through Interdisciplinary Innovation
“Addressing society’s most pressing challenges requires innovative, interdisciplinary thinking,” says Bruce Tidor, chief executive officer and interim director of SMART. Building on SMART’s long legacy as a hub for research and innovation in Singapore, WITEC harnesses expertise across engineering, medicine, AI, and materials science to push the boundaries of what is possible in health care.
This collaborative approach not only advances scientific discovery, but also creates real-world impact—benefiting Singapore, the United States, and aging societies worldwide.
Industry-Leading Precision Equipment Powering Breakthroughs
To support its ambitious goals, WITEC operates a state-of-the-art laboratory equipped with industry-leading tools. These include Southeast Asia’s first sub-micrometer resolution 3D printer and Singapore’s first Verasonics Vantage NXT 256 ultrasonic imaging system.
Unlike conventional 3D printers that work at millimeter or micrometer scales, WITEC’s printer achieves sub-micrometer precision, enabling fabrication at the scale of individual cells or tissue structures. This capability is critical for prototyping advanced bioadhesive materials and skin-safe device interfaces that can maintain stable, high-quality imaging over long durations.
Complementing this is the Verasonics imaging system, which offers a significantly larger number of probe control channels and a new transducer adapter. These features allow researchers to experiment with highly customized imaging methods, advanced beamforming techniques, and AI-driven diagnostics—capabilities not possible with standard hospital ultrasound equipment.
Together, these technologies dramatically accelerate the design, prototyping, and validation of WITEC’s wearable ultrasound system, enabling early demonstrations on phantoms and healthy subjects.
Transforming Chronic Disease Management With Wearable Ultrasound
Chronic diseases are rising rapidly worldwide, particularly among aging populations and individuals with multiple long-term conditions. This trend underscores the urgent need for effective home-based care solutions that go far beyond basic wellness tracking.
While consumer wearables like smartwatches provide useful metrics such as heart rate and activity levels, they lack the clinical depth required for chronic disease management. On the other hand, traditional ultrasound systems—though powerful—are bulky, operator-dependent, and confined to hospital settings, offering only brief snapshots in time.
WITEC bridges this gap by developing a wearable ultrasound imaging system that combines bioadhesive technology with AI-enhanced diagnostics. Capable of up to 48 hours of uninterrupted imaging, the system aims to support early detection, continuous monitoring, and home-based pre-diagnosis of chronic cardiovascular diseases.
Beyond improving patient outcomes, this innovation could also ease health-care workforce shortages, reduce hospital admissions, and lower long-term health-care costs by shifting monitoring from hospitals to homes and communities.
Leadership Driving the Vision Forward
WITEC is led by an internationally recognized team of co-lead principal investigators, including Xuanhe Zhao, Joseph Sung, Cher Heng Tan, Chwee Teck Lim, and Xiaodong Chen.
Their combined expertise spans materials science, AI diagnostics, biomedical engineering, data science, and clinical medicine—creating a powerful foundation for translational research.
From Research to Real-World Impact
Clinical trials led by Violet Hoon are expected to begin this year, validating long-term heart monitoring for chronic cardiovascular disease management. Over the next three years, WITEC aims to deliver a fully integrated wearable platform through innovations in bioadhesive couplants, nanostructured metamaterials, and ultrasonic transducers.
As MIT’s research enterprise in Singapore, SMART remains committed to advancing breakthrough technologies that address global challenges. WITEC builds upon SMART’s existing research portfolio across areas such as antimicrobial resistance, cell therapy, precision agriculture, AI, and 3D-sensing technologies—strengthening Singapore’s position as a global hub for biomedical innovation.
Why Continuous Ultrasound Monitoring Is a Game Changer for Elderly Care
For decades, ultrasound imaging has been one of the most powerful diagnostic tools in modern medicine—yet it remains largely episodic. Patients receive scans only during hospital visits, often after symptoms worsen. For elderly patients living with chronic cardiovascular conditions, this reactive model leaves dangerous gaps in monitoring.
Wearable ultrasound imaging fundamentally changes this paradigm. By enabling continuous cardiovascular visualization, clinicians can detect subtle physiological changes—such as fluid buildup, abnormal heart wall motion, or blood flow irregularities—days or even weeks earlier than traditional check-ups allow.
This proactive approach is especially critical for elderly patients, whose conditions can deteriorate rapidly and unpredictably. Continuous imaging supports earlier clinical decisions, medication optimization, and timely intervention, reducing emergency admissions and improving long-term outcomes.
From Smart Wearables to Clinical-Grade Imaging
Most consumer wearables today focus on surface-level metrics—heart rate, steps, sleep cycles, or oxygen saturation. While valuable, these data points lack direct anatomical and functional insight.
WITEC’s wearable ultrasound system moves beyond surface metrics by offering clinical-grade imaging in a form factor suitable for daily life. This positions it in an entirely new category—bridging the gap between hospital diagnostics and consumer health technology.
Unlike traditional ultrasound devices that require trained operators, WITEC’s system is designed for passive, long-duration use, allowing imaging data to be collected automatically and analyzed using AI-assisted models.
The Role of AI in Making Sense of Continuous Imaging Data
Continuous ultrasound imaging generates massive volumes of data. Making this information actionable requires advanced data science and artificial intelligence.
WITEC integrates AI-powered diagnostics to:
- Detect early patterns linked to heart failure progression
- Identify deviations from a patient’s personalized baseline
- Reduce clinician workload through automated interpretation
- Enable predictive alerts before symptoms become severe
By combining imaging with AI, WITEC aims to transform ultrasound from a diagnostic snapshot into a predictive clinical tool—one that supports decision-making in real time.
