While various antifogging approaches have been explored, achieving sustained transparency across diverse environments through a simple and scalable design remains a critical challenge in surface engineering. Herein, a structurally simple, low\u2010surface\u2010energy polydimethylsiloxane (PDMS) capped hydrogel micropillar arrays comprising poly(ethylene glycol) diacrylate (PEGDA) are introduced to achieve transparent superhydrophobic antifogging surfaces. The exposed sidewalls of hydrogel micropillars effectively absorb water vapor, while the low\u2010surface\u2010energy caps on the top offer superhydrophobicity with a high water contact angle (&gt;160\u00b0). It is demonstrated that this design effectively prevents fogging and exhibits self\u2010cleaning properties to maintain high optical transparency (&gt;84%), offering a scalable and effective solution for transparent substrates operating in diverse optical and environmental applications.<\/jats:p>","DOI":"10.1002\/smll.202509390","type":"journal-article","created":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T15:39:52Z","timestamp":1761147592000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Low\u2010Surface\u2010Energy
