Epidermal sensors
Epidermal systems based on ultra-thin and flexible electronics are promising next-generation wearable platforms that enable chronic monitoring of physiological signals in real-time. This long-term applicability is critical for chronic diseases that require constant recordings and on-demand therapeutic intervention directly through the skin.
Chemical sensors
Developing portable, miniaturized, and sensitive chemical sensor is essential for home healthcare and workplace safety. A capacitive micromachined ultrasound transducer (CMUT), a MEMS-based resonator that detects chemicals through the mass-loading mechanism, is suitable for the miniaturized chemical sensor systems due to its array structure, easy miniaturization, and high sensitivity. By coating CMUT devices with different chemically sensitive layers, multiplex detection of various chemical analytes such as volatile organic compounds (VOC) is possible, and CMUT-based chemical sensor systems serve as a promising platform for chemical monitoring applications.
