Abstract

Abstract:

The rapid ageing of populations and the global impact of the COVID -19 pandemic have exposed critical shortcomings in medical resources and healthcare systems, underscoring the urgent need for innovative biomedical technologies. Traditional centralized healthcare remains predominantly offline and reactive, with physiological monitoring occurring intermittently at clinical facilities. In contrast, recent advancements in smart materials, wearable technologies, wireless communication, artificial intelligence, and the Internet of Things are paving the way for a paradigm shift toward continuous, pervasive, and personalized digital health solutions. However, significant challenges persist in achieving advanced monitoring modalities, accessibility, and sustainability.

This talk will first present our recent progress in developing cost-effective, accessible sensing technologies for ambulatory monitoring of deep-tissue signals. I will introduce wireless, flexible near-infrared spectroscopy (NIRS) devices for measuring local hemodynamics and tissue oxygenation, mechano-acoustic sensors to decode tissue mechanics, and radio-frequency metamaterial sensors for non-contact vital sign detection. The second part of the talk will cover our recent efforts in developing flexible energy devices targeted at sustainable and reliable power sources for wearable bioelectronics. These works represent steps toward accessible, affordable, and continuous health monitoring, addressing diverse needs such as pediatric care, rehabilitation, and energy autonomy, and paving the way for pervasive and sustainable healthcare.
