Special Issue Information

Dear Colleagues,

Nanomaterials possess a large specific surface area and special physical, chemical and electrical properties. With the development of science and technology, and the arrival of artificial intelligence, flexible sensing materials and devices have gradually been integrated into people's lives. Starting from the original innovation of nanoscale sensing material synthesis and device structures, new flexible tactile sensors, flexible gas sensors, flexible photoelectric sensors and flexible electronic skin can be constructed. With the continuous development and progress of flexible wearable technology, its application becomes more and more extensive. At present, flexible sensing materials and devices have been applied to many fields, such as robotics, intelligent manufacturing, health data monitoring, wearable medical devices, and environmental sensing.

This Special Issue aims to provide a platform for researchers and related technologists to share their latest findings on nanomaterials in the field of flexible sensing and devices, promote multidisciplinary research in materials science, chemistry and electronics/biomedicine, and achieve interdisciplinary research and collaboration to contribute to the development of this field. The scope of this Special Issue ranges from the synthesis and characterization of new nanomaterials, the design and preparation of flexible sensors, the development and application of flexible sensors, etc.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but need not be limited to) the following:

  • Synthesis and characterization of new nanomaterials;
  • The design and preparation of flexible sensors;
  • The development and application of flexible sensors.

We look forward to receiving your contributions.

The construction of transition metal dichalcogenides (TMDs) heterojunctions for high-performance gas sensors has garnered significant attention due to their capacity to operate at low temperatures. Herein, we realize two-dimensional (2D) WS2 nanosheets in situ grown on one-dimensional (1D) In2O3 nanofibers to form heterostructures for formaldehyde (HCHO) gas sensors. Capitalizing on the p-n heterojunctions formed between WS2 and In2O3, coupled with the high surface-to-volume ratio characteristic of 1D nanostructures, the WS2/In2O3 NFs sensor demonstrated an elevated gas response of 12.6 toward 100 ppm HCHO at 140 °C, surpassing the performance of the pristine In2O3 sensor by a factor of two. Meanwhile, the sensor presents remarkable repeatability, rapid response/recovery speed, and good long-term stability. The superior sensing capabilities of WS2/In2O3 NFs heterojunction are attributed to the combined impact of the increased charge transfer and the presence of more sites for gas adsorption. The research endows a potent approach for fabricating TMD heterojunctions to significantly enhance the gas sensing properties of gas sensors at relatively low temperatures. Full article
