“…The study showed that the sensors exhibited a higher sensitivity to NO than other gases (C 2 H 5 OH, HCHO, H 2 S) at the optimal operating temperature of 200°C [66]. It also showed that the MEMS gas sensor with blue light illumination from the bottom of the sensors, showed that the blue light increased the carrier concentration in the ZnO nanowires [66]. The response value to 50 ppb NO gas was increased from 48.13% to 86.17% [66].…”

This paper presents the recent advances of the ZnO nanowires based sensors. ZnO has gained a substantial interest in the research areas of the wide band gap semiconductors due to its unique electrical, optical and structural properties. ZnO is considered as one of the major candidates for several electronic and photonic applications. ZnO is considered as a potential contender in optoelectronic applications such as solar cells, surface acoustic wave devices, and ultraviolet (UV) emitters. ZnO as a nanostructured material exhibits many advantages for nanodevices. ZnO nanostructured material has the ability to absorb the UV radiation. ZnO nanowires have received a considerable attention due to the morphological changes with doping. ZnO nanowires are very attractive material for nano-sensors due to their properties induced by the quantum size effects. Recently, ZnO nanowires based devices have gained much attention due to their various potential applications in nanoelectronics devices including gas sensors, nanogenerators, and nano-lasers. The recent aspects of ZnO nanowires based sensors devices are presented and discussed.

Wearable sensors have drawn considerable interest for healthcare applications due to their low cost, flexibility, lightweight, and biocompatibility. Gold nanomaterials possess excellent properties such as high conductivity/ flexibility, facile surface functionalization, biocompatibility, wide electrochemical sensing window, and extraordinary optical response, making them excellent candidates for wearable sensors. By implementing gold nanomaterials such as gold nanoparticles (AuNPs) and gold nanowires (AuNWs), great efforts are devoted to fabricate wearable sensors with rational designs for healthcare applications. This review focuses on recent advances in gold nanomaterials-implemented wearable sensors, particularly the fabrication method, the working mechanism, and the performance of these wearable sensors in healthcare-related applications. Wearable sensors including strain/pressure sensors, humidity/gas sensors, electrochemical sensors, and colorimetric sensors are discussed and highlighted. Meanwhile, future prospects and challenges are also discussed on the development of gold nanomaterials-implemented wearable sensors.
