It can crawl, flip, move upward to water surfaces, swim and steer on water, and transition seamlessly between terrestrial and aquatic environments. This amphibious multimodal locomotion is enabled by two distinct untethered actuation mechanisms under high-frequency alternating magnetic fields: i) thermally driven reversible bending deformation facilitated by ultrafast and programmable induction heating to achieve crawling, flipping, and surfacing motions; and ii) Lorentz force to power on-water swimming. Steerable crawling and swimming are achieved by spatially controlling the alternating magnetic fields. With these capabilities, multimodal amphibious locomotion of the soft robot over a hybrid terrestrial-aquatic environment is further demonstrated for targeted cargo transportation.

This study introduces a novel and sustainable class of Deep Eutectic Solvents (DESs) to demonstrate a dynamic (time-variant) mechanochemical effect, achieved through molecular electro-actuation at the fluid-to-solid interface. The dynamic micro-mechanochemical effect was demonstrated using a DES mixture consisting of citric acid and choline chloride in a 1:1 M ratio, applied to a nickel single-crystal micro-cantilever substrate. The findings show how the DES coating alone induced compressive surface stress, resulting in a 34 % increase in principal stress. More notably, when the substrate surface was polarized with a ±5 V potential, electro-actuation amplified this mechanochemical effect by up to 51 %, confirming a clear dynamic response. Further validation was presented at the macroscale in a polycrystalline material setting, where a similar response was observed. These findings give insight into the possible development of smart surfaces coated with DESs, where a single chemical system can dynamically alter materials’ mechanical response through simple electro-actuation, offering versatile applications across micro and macro scales.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"86 ","pages":"Pages 183-201"},"PeriodicalIF":21.1,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finite element analysis (FEA) is performed, suggesting that such shear-induced structures are capable of reversible post-assembly shape transformation among different modes.
