About
Arnaldo Leal-Junior is a prominent researcher specializing in optical fiber sensing technologies, with particular expertise in polymer optical fibers (POF), fiber Bragg gratings (FBG), and their applications in healthcare, robotics, and wearable devices. His work has garnered significant recognition, accumulating hundreds of citations across a concentrated and highly productive body of research. Leal-Junior has made substantial contributions to the development of innovative sensing systems that bridge advanced photonics with practical human-centered applications. His highly cited 2019 comprehensive review of polymer optical fiber sensors in healthcare (207 citations) established him as a key authority in the field. He has pioneered the integration of FBG sensors with 3D-printed structures to create customizable, cost-effective force and temperature sensors, and developed novel multi-parameter measurement approaches — notably achieving simultaneous axial strain, bending, and torsion detection using a single FBG in CYTOP fiber (112 citations). His wearable sensor systems for gait analysis and human-robot interaction assessment demonstrate a clear commitment to translating laboratory innovations into assistive technologies with real-world impact. Through his work on smart walkers, active orthoses, and diaphragm-embedded sensors, Leal-Junior has meaningfully advanced the intersection of optical sensing, rehabilitation engineering, and intelligent robotics.
