Which wall does your research break?

Through my research, I have successfully addressed the limitation in the sensing range of wearable sensors. Wearable sensors have revolutionized health and fitness monitoring by enabling continuous monitoring of the human body, providing a more accurate and comprehensive understanding of overall well-being. However, existing wearable sensors, which utilize thermal, electrical, and optical mechanisms, are confined to sensing signals from the skin surface or shallow tissues, usually within 5 mm of the skin. To overcome this limitation and explore new possibilities, my research pioneers the research of wearable sensors that aims to go deep into the human body. Our approach is to integrate ultrasound technology into the wearable platform. Through innovative material design and advanced manufacturing techniques, we have developed wearable ultrasound devices capable of penetrating as deep as 16 cm into the human body. This breakthrough opens up an entirely new sensing dimension for wearable sensors, allowing us to collect a wide range of signals from deep tissues, including the muscular skeleton, central vasculature, and most importantly, visceral organs. Our wearable ultrasound technology enables continuous and noninvasive monitoring of deep tissues within the human body, marking a significant advancement in both fundamental research and clinical applications. By delving deep into the human body, we gain valuable insights into health conditions and physiological functions, which hold great potential for enhancing medical understanding and improving patient care.

What inspired or motivated you to work on your current research or project?

My inspiration behind working on the wearable ultrasound technology was a combination of various factors, including the desire to push the technological boundary, explore new scientific frontiers, and create meaningful innovations with the potential to positively impact people’s lives. From a technological standpoint, the limitations of existing wearable sensors in capturing only surface signals have been a prominent challenge within the wearable community. By integrating ultrasound into the wearable platform, I sought to overcome this limit and gain a deeper understanding of the human body’s intricate inner workings. The incorporation of wearable ultrasound devices offers the potential for offering comprehensive insights into one’s health, going beyond what traditional wearable sensors can provide. Scientifically, the prospect of continuously and noninvasively monitoring deep tissues, especially during motion, presented an exciting and unexplored realm of study. Medical evidence suggests that deep tissue signals may hold stronger and quicker correlations to disease status and prognosis. For example, regional wall motion abnormalities in the heart can be detected earlier than conventional electrocardiogram measurements on the skin surface to predict myocardium ischemia. Wearable ultrasound technology opens up a world of opportunities to systematically and accurately investigate the relationship between such deep tissue signals and various diseases, unlocking new avenues for medical research. Within the field of medicine and healthcare, I found immense inspiration in the vast potential applications of wearable ultrasound technology. Clinical ultrasound devices are often rigid and bulky, requiring skilled clinicians for one-time measurements. This user dependency can lead to varying diagnoses and interpretations. In contrast, wearable ultrasound technology allows for continuous monitoring, offering a more comprehensive and objective assessment of an individual’s health status. By incorporating electronic scanning and artificial algorithms for image interpretation, the need for user dependency is eliminated, making diagnoses and monitoring more consistent and cost-effective. Furthermore, the hands-free nature of wearable ultrasound devices streamlines the scanning process, democratizing access to healthcare. This accessibility ensures that more people can benefit from objective and accurate medical assessments, regardless of their location or available resources. By democratizing healthcare through wearable ultrasound technology, we can strive towards a future where improved diagnostics, treatment monitoring, and chronic condition management become accessible to a broader population, positively impacting lives and enhancing overall healthcare outcomes.
