Aligned liquid crystal elastomer structures for mechanical damping

Patent published on the 2026-06-11 in US under Ref US20260159710 by OREGON STATE UNIV [US] (Cook Adam W [us], Leguizamon Samuel C [us], Bischoff Adam [us], Roach Devin [us])

Abstract: Direct ink write (DIW) 3D printing, an extrusion-based additive manufacturing (AM) approach, is used to prepare aligned, monodomain liquid crystal elastomer (LCE) lattice structures which can be used for multi-strain rate mechanical damping, ranging from quasi-static compression to dynamic shock and vibration. LCE structures can not only dissipate strain energy in quasi-static environments because of their lattice architectures, but also harness the dynamic energy dissipation properties of the a[...]


Our summary: Aligned liquid crystal elastomer structures are fabricated using direct ink write 3D printing. These structures enable effective mechanical damping across various strain rates. The invention enhances energy dissipation capabilities in both quasi-static and dynamic environments.

Published on 2026-06-02 by Chon-Teng Belmiro Chu, Hao-Chung Chen, Ting Hsu, Hsiang-Yu Lo, Ming-Shien Chang and Guin-Dar Lin @IOP SCIENCE

Abstract: We present a quantitative, geometry-resolved framework to evaluate the effects of patch-potential noise in realistic three-dimensional Paul-trap structures. As a concrete application, we analyze a skeleton-electrode architecture and compare its performance against a conventional blade trap under identical ion-to-electrode distances and matched confinement parameters. The skeleton geometry achieves a suppression of motional heating exceeding 50%, with heating rate ratios of for the axial mode and[...]


Our summary: A geometry-resolved framework evaluates patch-potential noise in Paul-trap structures. The skeleton-electrode architecture reduces motional heating by over 50% compared to conventional designs. Heating maps reveal noise contributions primarily from surfaces within 500 µm, guiding effective electrode reconfiguration strategies.
