    Abstract

    Surface acoustic wave (SAW) sensors have attracted great attention worldwide for a variety of applications in measuring physical, chemical and biological parameters. However, stability has been one of the key issues which have limited their effective commercial applications. To fully understand this challenge of operation stability, this paper systematically reviewed mechanisms, stability issues and future challenges of SAW sensors for various applications.
    This review paper starts from different types of SAWs, advantages and disadvantages of different types of SAW sensors, and then stability issues of SAW sensors. Then recent efforts made by researchers for improving working stability of SAW sensors are reviewed. Finally, it discusses the existing challenges and future prospects of SAW sensors in the rapidly growing Internet of Things (IoT) enabled application market.
