“…Fluorescence-based temperature sensors utilize a single fiber to transmit both excitation and emission signals. The advantage of self-calibrating [ 123 ] attracts the interest of many researchers. The characteristic of tunable fluorescence emission under temperature variations can be employed in fluorescence-based temperature sensors.…”

Concrete is the most commonly used construction material nowadays. With emerging cutting-edge technologies such as nanomaterials (graphene, carbon nanotubes, etc.), advanced sensing (fiber optics, computer tomography, etc.), and artificial intelligence, concrete can now achieve self-sensing, self-healing, and ultrahigh performance. The concept and functions of smart concrete have thus been partially realized. However, due to the wider application location (coastal areas, cold regions, offshore, and deep ocean scenarios) and changing climate (temperature increase, more CO2 emissions, higher moisture, etc.), durability monitoring (pH, ion penetration, carbonation, corrosion, etc.) becomes an essential component for smart concrete. Fiber optic sensors (FOS) have been widely explored in recent years for concrete durability monitoring due to their advantages of high sensitivity, immunity to harsh environments, small size, and superior sensitivity. The purpose of this review is to summarize FOS development and its application in concrete durability monitoring in recent years. The objectives of this study are to (1) introduce the working principle of FOS, including fiber Bragg grating (FBG), long-period fiber grating (LPFG), surface plasmon resonance (SPR), fluorescence-based sensors, and distributed fiber optic sensors (DFOS); (2) compare the sensitivity, resolution, and application scenarios of each sensor; and (3) discuss the advantages and disadvantages of FOS in concrete durability monitoring. This review is expected to promote technical development and provide potential research paths in the future for FOS in durability monitoring in smart concrete.

“…Acridones have rather high luminescence quantum yields and are known as efficient laser dyes 36 and fluorescence sensors. 37,38 Due to the acridone emission maximum close to 500 nm, branched conjugated units with acridone bridges are advantageous for conducting and fluorescent materials. The benefits of such heterocyclic structures include chemical inertness, notable resistance to photobleaching and also the possibility to be excited around 400-420 nm.…”

Conjugated arylenes have significant perspectives as active materials useful in electronics, i.e. as semiconductors or solar cells. Organic semiconductors maintain the related processability, as with polymers, while retaining optoelectronic characteristics, i.e., high absorption coefficients of photons in the visible-region. This review summarizes recent developments in semiconducting polymers for electronic tools. This includes information on substitution and localization, branching, and its impact on functional materials.

“…Optical fibers have received a great deal of attention because of many advantages such as light‐weight, low‐cost, ease of handling, and immunity from electromagnetic noise. Optical fiber sensors demonstrated over the past decades were intended for the detection of physical and chemical properties such as strains [1, 2], temperatures [3, 4], pH [5, 6], gas [7] and so on. In particular, there were many reports of fiber optic relative humidity sensors [8–11].…”

An optical lensed fiber for detecting respiration condition in the vicinity of nose has been proposed and been demonstrated to work as a breath sensor. For simple preparation and larger sensing area, a piece of about quarter‐pitch of an optical gradient index fiber (GIF) tip was spliced to the end of a single mode fiber. The sensing principle is based on the change of back reflection intensity caused by attachment of water molecules on the GIF tip during respiration. The experimental results showed that this breath sensor operated with a good sensitivity and a real‐time respiration monitor was presented. In terms of the tiny size and light weight, the optical lensed fiber breath sensor is potential for the application of monitoring breathing condition in hospital and in home care. © 2012 Wiley Periodicals, Inc.
