Micropillar Arrays: Enhancement of Magneto‐Mechanical Actuation of Micropillar Arrays by Anisotropic Stress Distribution (Small 38/2020)

Jeong Eun Park, Jisoo Jeon, Sei Jin Park, Sukyoung Won, Zahyun Ku, Jeong Jae Wie

Abstract

In the article number 2003179, Jeong Jae Wie and co-workers report enhanced twisting or bending actuation of rectangular micropillars containing pre-programmed horizontal or vertical magnetic particle alignment. Anisotropic stress distributions of rectangular pillars drastically enhance magneto-mechanical actuation of micropillars in comparison to square micropillars. Magnetically deformed micropillars are selectively shape-fixed by local evaporative assembly of polymeric solution even after removal of the magnetic field.
