Surface acoustic waves (SAWs) are the guided waves that propagate along the top surface
of a material with wave vectors orthogonal to the normal direction to the surface. Based on …

pH-sensing materials and configurations are rapidly evolving toward exciting new
applications, especially those in biomedical applications. In this review, we highlight rapid …

Corrosion has been a great concern in the oil and natural gas industry costing billions of
dollars annually in the US The ability to monitor corrosion online before structural integrity is …

Screen-printed sensing electrodes attract much attention for water pollution monitoring due
to their small size, physical and chemical durability, and low cost. This paper presents the …

The present study is concerned about the development of highly sensitive and stable
microfluidic pH sensor for possible identification of circulating tumor cells (CTCs) in blood …

Acid–base homeostasis (body pH) inside the body is precisely controlled by the kidneys and
lungs and buffer systems, such that even a minor pH change could severely affect many …

In this work, a new flexible and biocompatible microfluidic pH sensor based on surface
acoustic waves (SAWs) is presented. The device consists of polyethylene naphthalate (PEN) …

Surface acoustic wave (SAW) sensors containing graphene–nickel (Ni)–L-alanine
composite sensing films for carbon dioxide (CO2) detection were investigated. ST-cut quartz …

In this paper, we propose fast, highly sensitive, and wide-dynamic-range fiber-optic probe-
type biosensors to detect pH and glucose. The operation principle of the proposed …

We investigated an extended-gate field-effect transistor (EG-FET) as a pH sensor in this
work. It was based on low-temperature hydrothermally grown one-dimensional (1-D) zinc …
