About
Lennart Leffers is a researcher advancing the field of optical fiber sensing, with a focus on polymer optical fibers for mechanical measurement applications. His key research areas include fiber Bragg grating technology, bend and strain sensors, and the development of flexible, elastic optical components for movement detection. Leffers’ major contribution is the design and demonstration of a novel optical bend sensor based on eccentrically micro-structured multimode polymer optical fibers, as reported in his most-cited 2021 paper. This work introduces a simple yet effective concept—inscribing eccentric Bragg gratings into graded-index polymer fibers—to achieve high flexibility and sensitivity for measuring bending and movement. With 11 citations, this paper has established a foundation for low-cost, durable sensing solutions in wearable technology and structural health monitoring. Leffers’ research stands out for its practical approach to integrating optical sensing into flexible materials, offering promising avenues for real-world applications in biomechanics and robotics. His work continues to inspire innovations in polymer-based photonic sensors.
