We present a portable and low-cost system for interrogation of long-period fiber gratings
(LPFGs) costing around a 30th of the price of a typical setup using an optical spectrum …

The use of advanced sensing devices for concrete and reinforced concrete structures (RCS)
is considered a rational approach for the assessment of repair options and scheduling of …

This study introduced an optical fiber core sensor designed to measure chloride ions by
removing the fiber's coating and cladding, allowing direct interaction between the fiber core …

Structural health monitoring (SHM) is crucial for preventing and detecting corrosion, leaks,
and other risks in reinforced concrete (RC) structures, ensuring environmental safety and …

A new and selective voltammetric method for chloride determination is proposed, based on
