Fiber-Tip Microgripper with Sub-Milliwatt Photoactuation (Advanced Optical Materials 16/2025)

Abstract

Micromanipulation

A fiber-tip microgripper manipulates objects using its azobenzene liquid crystal polymer fingers, which are actuated by milliwatt-level visible light delivered directly through the optical fiber. This simple design offers significant advantages, including low power consumption, seamless integration with fiber-optic systems, and the ability to operate in confined spaces. This makes it a promising tool for applications in robotics, biomedicine, and microfluidics. More details can be found in article 2402565 by Tsung-Hsien Lin and co-workers.
