Bionic　microrobots　working　in　liquid　environments　have　attracted　attention　in　recent　years,　because　they　play　an　important　role　in　the　medical　fields.　So　far,　most　bionic　microrobots　serving　in　liquid　environments　(swimming　microrobots)　are　fabricated　based　on　organic　materials.　Limited　by　the　inherent　property　of　organic　materials,　the　performance　and　lifetime　of　the　swimming　microrobots　are　still　deficient.　Facing　this　challenge,　inspired　by　sperms,　swimming　microrobots　based　on　the　inorganic　phase　transition　driving　material　vanadium　dioxide　are　developed.　In　liquid　environments,　the　linear　and　rotary　motion　of　these　sperm-like　micro-robots　could　be　controlled　by　changing　the　laser　modulation　frequency.　The　highest　linear　speed　attained　is　56　mu　m　s-1,　and　the　highest　rotary　speed　attained　is　14　degrees　s-1.　The　microrobot　is　able　to　undergo　more　than　105　cycles　in　a　liquid　environment　without　degradation　of　its　performance.　Considering　its　high　performance　and　controllability,　the　swimming　microrobot　is　expected　to　be　helpful　in　medical　applications　such　as　precision　drug　delivery　and　minimally　invasive　surgery.　Inspired　by　the　sperm,　photo-driven　microrobots　serving　in　liquid　environments　are　developed.　The　linear　and　rotary　motion　of　sperm-like　micro-robots　could　be　controlled　by　laser　frequency.　The　highest　linear　and　rotary　speeds　attain　56　mu　m　s　and　14　degrees　s-1.　The　microrobot　undergoes　more　than　105　cycles　in　liquid　environments　without　performance　degradation.image　(c)　2024　WILEY-VCH　GmbH
