“…IoT connect all systems for communications and intelligent controls (Suresh et al , 2022; Chen et al , 2018). For example, a remote raw water monitoring and control system was developed as Internet of Water Things (IoWT) by researchers (Júnior et al , 2021). A two-layer energy-efficient framework using wireless SAW sensor network for leakage detection in monitoring water distribution system was proposed (Tang and Wu, 2014).…”

Purpose 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 aims to systematically review mechanisms, stability issues and future challenges of SAW sensors for various applications. Design/methodology/approach This review paper starts with different types of SAWs, advantages and disadvantages of different types of SAW sensors and then the stability issues of SAW sensors. Subsequently, 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-enabled application market. Findings A large number of scientific articles related to SAW technologies were found, and a number of opportunities for future researchers were identified. Over the past 20 years, SAW-related research has gained a growing interest of researchers. SAW sensors have attracted more and more researchers worldwide over the years, but the research topics of SAW sensor stability only own an extremely poor percentage in the total researc topics of SAWs or SAW sensors. Originality/value Although SAW sensors have been attracting researchers worldwide for decades, researchers mainly focused on the new materials and design strategies for SAW sensors to achieve good sensitivity and selectivity, and little work can be found on the stability issues of SAW sensors, which are so important for SAW sensor industries and one of the key factors to be mature products. Therefore, this paper systematically reviewed the SAW sensors from their fundamental mechanisms to stability issues and indicated their future challenges for various applications.

“…This paper proposes to utilize pH as the sensing parameter by analyzing the relationship between the delay time and the change in pH. However, other sensing parameters do exist and can also be used to quantitatively measure the water quality namely the turbidity, Oxidation Reduction Potential (ORP), electrical conductivity, temperature, salinity, and chlorophyll-a concentration [34], [35]. For the case when multiple parameters are to be targeted, one sensor-tag for one parameter approach has to be used.…”

A water quality monitoring application often requires the deployment of Internet of Things (IoT) sensors over a wide water body with communication links among them to transmit, receive the data, and then uplink it to the cloud for further analytics. Deployment of this kind requires battery-assisted IoT sensors which require monitoring the battery level and replacement when necessary. It is thus desirable to have battery-free sensortags and a suitable communication infrastructure to obtain data. In this paper, a system that facilitates obtaining sensed data, like pH, through passive sensor-tags based on Surface Acoustic Wave (SAW) technology and a cellular code-reuse scheme based reader infrastructure is proposed. The reader in each cell is able to read multiple sensor-tags simultaneously, which itself has been a challenge. The SAW sensor tags are appropriately proposed to be designed to be orthogonal to allow simultaneous detection and the cell range of reader-SAW sensor-tags communication is sought to be further enhanced through a resonant loading of Interdigital Transducer (IDT) based reflectors.
