Special Issue Information

Dear Colleagues,

Sensors for measuring pH have wide applications, ranging from water to health to environmental monitoring. pH is an important indicator of the quality of water and health conditions. Recently, considerable interest has been shown for wearable sensors for the early prediction of diseases through the non-invasive analysis of bodily fluids like sweat, saliva, and urine. Appropriate pH assures drinking water safety, the survivability of marine organisms, and homeostasis maintenance. pH in harsh conditions, such as mining and waste water, is critical and may severely affect the environment. The precise measurement of pH is crucial for such applications. Consequently, a wide range of pH sensing techniques ranging from optical to electrochemical to physicochemical methods have been developed. Structural and sensing materials including metal, metal oxides, polymers, semiconductors, as well as nanomaterials (i.e., nanoparticles, nanotubes, and two-dimensional (2D) materials), which need to be identified and connected in small form to create integrated pH systems.

The aim of this Special Issue on pH sensors for water and health monitoring applications is to offer the latest cutting-edge research and development of pH sensor technologies for water and health monitoring. This issue seeks to publish recent advances in the fabrication of wearable pH sensors, water pH sensors, environmental (i.e., mining) pH sensors, precision sensing performance, and integration challenges. Both experimental and theoretical articles will be published in this Special Issue, focusing on the current-state-of-the-art pH sensing materials, sensing techniques, sensing mechanisms, and the engineering and development of small footprint integrated sensors for the precise measurement of pH in water and wearable sensing applications.
