“…The low-cost interrogator circuit consists of a pigtailed photodiode (FDSP625, Thorlabs), dual-stage amplifiers, two Arduino Uno microcontroller boards, and two wireless transceiver modules (nRF24L01+), with a total build cost of ≤USD 250. The detailed operation principles of TIA was described previously in our work [31]. Here, an updated design of the dual-stage TIA is shown in Figure 6a.…”

“…Raghavan et al [30] designed a wavelength-resolving detector that integrates a position-sensitive photodetector with a dispersive-filter-coated detector to serve as a low-cost FBG interrogator. Our previous works proposed a design of low-cost and wireless interrogation based on a photodiode-TIA circuit that converts optical signals into simple electrical signals [31]. Here, we further incorporate a dual-stage amplifier design with a low-pass filter to account for temperature response time and optical response resolution of the plasmonic sensor.…”

Reflection fiber temperature sensors functionalized with plasmonic nanocomposite material using intensity-based modulation are demonstrated for the first time. Characteristic temperature optical response of the reflective fiber sensor is experimentally tested using Au-incorporated nanocomposite thin films deposited on the fiber tip, and theoretically validated using a thin-film-optic-based optical waveguide model. By optimizing the Au concentration in a dielectric matrix, Au nanoparticles (NP) exhibit a localized surface plasmon resonance (LSPR) absorption band in a visible wavelength that shows a temperature sensitivity ~0.025%/°C as a result of electron–electron and electron–phonon scattering of Au NP and the surrounding matrix. Detailed optical material properties of the on-fiber sensor film are characterized using scanning electron microscopy (SEM) and focused-ion beam (FIB)-assisted transmission electron microscopy (TEM). Airy’s expression of transmission and reflection using complex optical constants of layered media is used to model the reflective optical waveguide. A low-cost wireless interrogator based on a photodiode transimpedance-amplifier (TIA) circuit with a low-pass filter is designed to integrate with the sensor. The converted analog voltage is wirelessly transmitted via 2.4 GHz Serial Peripheral Interface (SPI) protocols. Feasibility is demonstrated for portable, remotely interrogated next-generation fiber optic temperature sensors with future capability for monitoring additional parameters of interest.

In this work, we demonstrate a reflection-based nanocomposite-functionalized fiber H2 sensor for ease of installation and H2 sensing in energy storage, fuel cells, electrolyzers, and other similar devices. High-temperature H2 fiber probes decorated with Au-Pt bimetallic alloy nanoparticles (NPs) in rutile titania matrix are characterized with scanning electron microscopy (SEM) and grazing incidence X-ray diffraction (GIXRD), and tested experimentally with varying H2 concentration and cycling gas conditions. In response to reducing H2, fully reversible reflectance intensity changes at the alloy NPs' localized surface plasmon resonance (LSPR) absorption peak are demodulated in real-time. The reflection fiber probe coated with bimetallic Au-Pt NPs in titania show 15x higher sensitivity than corresponding monometallic Au NPs in titania. The demonstration of reflection hydrogen fiber probe provides an installation advantage in various reactor environment applications, and the investigation of the Au-Pt binary alloy system unfolds new sensitivity-enhancing pathways for NP-based LSPR modulation in reducing H2 environment at high temperatures.

“…As far as the primary mechanism is concerned, an increase in temperature leads to an increase in resistivity of Au, which elevates the temperaturedependent electron-phonon collision frequency, modifying the absorption as a function of wavelength. Detailed discussion of the temperature dependence of plasmonic nanocomposite-based fiber sensors can be found in prior literature for both evanescent wave absorption spectroscopy [27], [28], [31] and reflection probe configurations [29].…”

Electrical system monitoring applications are of increasing importance given recent trends towards electrification driving adoption of renewables and electric vehicles, for example. Thermal and acoustic signatures play an important role in health monitoring while electrical and magnetic field signatures can provide information about operational state. Optical fiber sensors are of particular interest for electrical system applications because of the compatibility with deployment in electrified systems without concerns for electromagnetic interference (EMI) or additional potential risks due to the presence of electrical sensor wires or power at the sensing location, particularly for medium voltage electrical systems. In this presentation, an overview of recent work in optical fiber-based sensing for electrical asset monitoring applications will be discussed in detail. Plasmonic sensors integrated with engineered nanomaterials will be discussed for thermal and other health monitoring applications while interferometric sensors will be discussed for acoustics and also magnetic fields and electrical current sensing. New directions in fiber-based sensing applications will also be discussed moving into the future.
