摘要

检测微柱和微纤维的弯曲刚度具有挑战性，因为它们很短且难以处理。我们开发了一种磁转矩方法，其中线圈产生的均匀磁场作用于附着在光纤端部的磁微棒上，迫使其转动。结果表明，磁转矩使微纤维弯曲成圆弧，圆弧半径取决于微纤维的弯曲刚度。采用在钨微细线上电镀镍的方法制备了磁性微棒。用合成微纤维对该方法进行了验证。在毫米宽的光斑内提供均匀磁场的光学显微镜可用磁台来研究各种束状微结构。

Magnetic torque-based method for quantifying the flexural rigidity of microfibers

Probing the flexural rigidity of micropillars and microfibers is challenging as they are short and difficult to handle. We developed a magnetic torque methodology where a coil-generated uniform magnetic field acts on a magnetic microrod attached to the fiber end, forcing it to turn. It is shown that magnetic torque bends microfibers in a circular arc, whose radius depends on the flexural rigidity. Magnetic microrods were fabricated by electroplating nickel on tungsten microwires. The methodology was validated with synthetic microfibers. Available magnetic stages for optical microscopes offering uniform magnetic fields within a millimeter-wide spot can be implemented to study a variety of beam-like microstructures.

期刊介绍： In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research. Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science. With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
