Stretch-induced reversible self-growth of high aspect ratio microstructures scribed by femtosecond laser - Nature Communications
2+ day, 1+ hour ago (1086+ words) As the pre-stretch ratio decreases from 1.67 to 1.098, the spacing between adjacent micropillars reduces from 805 to 497m (Fig.3d). Notably, the micropillar spacing remains constant throughout all stretching'release cycles (Fig.3e), confirming the geometric reversibility and mechanical stability of the self-grown micropillars. Overall, our…...
