Sensitive devices that are capable of converting different physical, chemical or biological stimuli, e.g. mechanical, thermal, acoustic, gaseous, biological and optical signals into electrical response, are of great potential for man-made robots to perceive the world like human beings, or assisting people to explore the fields that currently cannot be touched, or making our life more comfortable and protecting us from danger. According to their sensitive feature, they could be classified as temperature-sensitive, gas-sensitive, voltage-sensitive, and optical-sensitive materials and so on. Correspondingly, they are manufactured as thermistors, gas sensors, varistors, biosensor and optical sensor. The main trends in the development of sensitive materials and devices with high performance include low-dimensional and high-dimensional designs, low-temperature and facile preparation strategies, chip-type integration approaches, flexible and stretchable features and multi-functional modules. This symposium focuses on multifunctional nanomaterials and heterostructures for sensing devices. It covers the application of multifunctional nanomaterials and heterostructures for the development of high-performance sensing devices, such as gas sensors, optical detectors, thermistors, biosensor and pressure sensors. It will delve into the latest research advancements in the design, fabrication, characterization and application of various heterostructures and multifunctional nanomaterials for use in sensing devices. Research papers on newly emerged sensitive materials, progresses in preparation and characterization techniques, and new applications of sensitive materials and devices are all welcomed.
