Special Issue Information

Dear Colleagues,

In recent years, surface acoustic wave (SAW) sensors and humidity sensors have gained significant attention due to their applications in diverse fields, such as environmental monitoring, industrial automation, healthcare, and smart systems. These sensors offer several advantages, including high sensitivity, fast response times, and the ability to be integrated into wireless systems, making them indispensable in the development of advanced IoT and smart sensing technologies. The combination of SAW technology with novel materials has led to the creation of highly selective sensors capable of detecting a wide range of analytes, such as gases, humidity levels, and biological substances, with impressive precision.

This Special Issue seeks contributions that explore the latest advancements in SAW sensors and humidity sensors, from material innovations to fabrication techniques, signal processing, and their integration into practical applications. Topics of interest include, but are not limited to, new sensor designs, material optimization, device characterization, and real-world deployment. Contributions focusing on sensor performance enhancement, new sensing mechanisms, novel application fields, integration with IoT technologies, and low-cost production of these sensors are especially welcome.

Benefitting from high sensitivity, rapid response, and cost-effectiveness, surface acoustic wave (SAW) sensors have found extensive applications across various fields, including biomedical diagnostics, environmental monitoring, and industrial automation. Recently, low-dimensional materials have shown great potential in enhancing the performance of SAW sensors due to their exceptional physical, optical, and electronic properties. This review explores recent advancements in the fundamental mechanisms, design, fabrication and applications of SAW sensors based on low-dimensional materials. Specifically, the utilization of low-dimensional materials, including zero-, one- and two-dimensional materials, as sensing materials in SAW sensors are summarized. Their applications in SAW-based gas sensing, ultraviolet light sensing, humidity sensing, as well as biosensing are discussed. Furthermore, major challenges and future perspectives regarding employing low-dimensional materials to enhance SAW sensors are highlighted, providing valuable insights for future research and development in this field.
