Front Cover: In article number 2100222 by Rachel C. Steinhardt and co-workers, a soft actuation system is described, based on a new core-shell thermally-expandable microparticle, made of isobutane core and polystyrene shell, linked to a photothermal nano-transducer, gold nanoparticles, resulting in a core-shell-shell nanohybrid. The particles expand in photothermal and thermal milieus, and are able to power the movement of a composite elastomeric soft robot sample.

由多壳聚苯乙烯粒子-金纳米粒子纳米杂化物制成的微米级软致动器

封面：Rachel C. Steinhardt 及其同事在文章编号 2100222 中描述了一种软驱动系统，该系统基于一种新的核壳热膨胀微粒，由异丁烷核和聚苯乙烯壳制成，与光热纳米换能器，金纳米粒子，产生核-壳-壳纳米混合物。这些粒子在光热和热环境中膨胀，并能够为复合弹性软机器人样品的运动提供动力。
