About
Jan P. F. Lagerwall is a leading figure in soft matter physics, whose research centers on liquid crystals (LCs) and their transformation into functional materials for advanced technologies. His major contributions lie in harnessing the unique properties of cholesteric liquid crystals and liquid crystal elastomers (LCEs) to create innovative actuators, sensors, and optical devices. Lagerwall pioneered the development of cholesteric spherical reflectors (CSRs), which exploit omnidirectional chiral Bragg diffraction to produce narrow-band retroreflectors with distinct circular polarization—a breakthrough enabling unclonable, human-invisible machine vision markers and hidden information encoding on surfaces. His work on LCE shell actuators, including those with negative order parameters, introduces new paradigms for soft robotics and microfluidics, while his electrospun composite LCE fibers and tubular peristaltic pump actuators demonstrate scalable, practical fabrication methods. With his most-cited paper, "Cholesteric Liquid Crystal Shells as Enabling Material for Information‐Rich Design and Architecture," accumulating over 130 citations, Lagerwall’s research has profound implications for information technology, biomedical systems, and security. His achievements underscore a career dedicated to translating fundamental liquid crystal science into real-world, transformative applications.
