Welcome to Heng Research Group!
Welcome to Heng Research Group!
We leverage micro/nano- and flexible-electronic fabrication strategies to establish foundational technologies for next-generation microsystems, addressing key challenges in in situ chemical and biological analysis under complex environmental conditions and enabling innovative applications.
Research
Our group conducts research on bio-chem-analytical microelectronic systems, in situ sensing in complex environments, and integrated micro-nanotechnologies. Our work focuses sensor development, device design, system integration and application innovation, with the aim of advancing analytical technologies toward miniaturization, continuity, automation, and intelligence for applications in healthcare, human–machine interaction, environmental monitoring, and beyond.
Features
(1) μm-mm scale miniaturized sensing interfaces,
(2) μW-level low-power operation enabling self or wirelessly powered systems,
(3) mm-scale systems and even monolithically integrated platforms,
(4) Diverse and impactful application-driven technologies,
(5) Breath sensing related technologies and applications.
