Abstract
Smart and wearable electronic systems are promising for personal healthcare in near future. For smart health technology, various sensor-integrated portable, mobile and wearable systems have been extensively developed. Recently many sensor devices are being integrated into smartphone, which enables analysis of biomarkers from various body fluids and monitoring of physiological parameters. And many wearable sensor-integrated systems including skin-attachable platform which can monitor physiological signs, detect biomarkers for disease diagnosis and monitor the patients with chronic diseases have been extensively investigated. Here, I will discuss imaging-based fluorescence biosensors for highly sensitive detection of biomolecules and pathogenic bacteria which can be integrated with smartphone or portable IOT systems. In addition, I will present our recent works on stretchable wearable physical sensors (strain, pressure, and temperature), chemical sensors (gas) and biosensors (metabolite, protein) based on low-dimensional nanoscale materials (0D, 1D and 2D), nanocomposites or their hierarchical nanohybrids in FET, resistor or electrochemical device structures. Finally, future prospects in the development of the sensors for smart healthcare will be discussed.
