However, they still face challenges like size\u2010dependent detachment and the absence of continuous adhesion control. Here, we propose a two\u2010way shape\u2010memory micropillar array (SMMA) based on liquid crystalline elastomers (LCEs), reversibly and continuously switching between upright and collapsed states under thermal stimulation. By leveraging strong elastic energy released during spontaneous shape change and excellent mechanical strength, the surface enables in situ self\u2010driven detachment of microparticles larger than the pillar spacing. A heat\u2010load\u2010shear\u2010pull (HLSP) protocol is further developed to achieve efficient detachment of microparticles comparable to pillar spacing, with a detachment efficiency of 90.6% for glass microparticles. Optimization of preload depth and shear distance confirms adaptability across multiple particle materials and size ranges. These switchable adhesion capabilities are demonstrated in diverse applications including patterned transport and cyclic handling of microparticles. Overall, shape\u2010memory\u2010assisted shear adhesion provides a programmable route to precise manipulation and flexible transport of micro\u2010objects.<\/jats:p>","DOI":"10.1002\/smll.74910","type":"journal-article","created":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T10:20:21Z","timestamp":1785320421000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Two\u2010Way
