Inherently Flexible Sn1-xSbxO2 Solid Solution Nanofibers with Light-Driven Plasmon for Wearable Room-Temperature Gas Sensors.
The rapid advancement of the Internet of Things technology has driven a significant demand for wearable and portable gas sensors. However, the inherent brittleness and rigidity of inorganic resistive metal oxide semiconductors (MOSs) limit their flexibility in wearable sensor applications. Herein, for the first time, we present a novel approach to address these limitations by developing inherently flexible gas sensors using electrospun Sn1-xSbxO2 solid solution nanofibers. The self-supported nanofiber membranes exhibit remarkable inherent flexibility, which can be attributed to their ultrafine grain size and hybrid amorphous-crystalline structure that effectively mitigates the formation of macroscopic cracks within the Sn1-xSbxO2 nanofibers. Furthermore, these Sn1-xSbxO2 solid solution nanofibers demonstrate pronounced surface plasmon resonance absorption in the visible-light spectrum, enabling visible-light-driven room-temperature detection of nitrogen dioxide (NO2) at parts-per-billion (ppb) levels, which enhances their applicability for wearable devices. Additionally, the unique nanofiber network structure significantly improves air permeability, thereby facilitating gas sensing reactions while enhancing user comfort. These findings pave the way for the development of wearable real-time gas monitoring technologies, addressing critical challenges within the gas sensing field.
期刊介绍:
ACS Sensors is a peer-reviewed research journal that focuses on the dissemination of new and original knowledge in the field of sensor science, particularly those that selectively sense chemical or biological species or processes. The journal covers a broad range of topics, including but not limited to biosensors, chemical sensors, gas sensors, intracellular sensors, single molecule sensors, cell chips, and microfluidic devices. It aims to publish articles that address conceptual advances in sensing technology applicable to various types of analytes or application papers that report on the use of existing sensing concepts in new ways or for new analytes.
