Featured Application This article is an extensive overview of the different types of in-fiber
interferometric-based sensors and their technology. Abstract In-fiber interferometric-based …

Wound assessment is usually performed in hospitals or specialized labs. However, since
patients spend most of their time at home, a remote real time wound monitoring would help …

Hydrogel-integrated optical fiber sensors have garnered momentous interest due to their
optical properties, biocompatibility, and biodegradability. Integrating active materials with …

A temperature and humidity sensor based on photonic crystal fiber (PCF) coated with
graphene oxide (GO) cascaded with two spherical structures is presented and …

Carbon dioxide (CO 2) monitoring in human subjects is of crucial importance in medical

This study presents a label-free and efficient method for the diagnosis of collagen-IV by
using an optical fiber-based Mach-Zehnder interferometer (MZI) structure. The structure of …

Amidst the global trend of advancing renewable energies toward carbon neutrality, energy
storage becomes increasingly critical due to the intermittency of renewables. As an …

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 …
