Fig. 3: Reversible tuning of stretch-induced self-grown straight micropillars.

a Side view optical images and corresponding simulations of a micropillar varying stretching ratio from 1.67 to 1. b Heights of micropillars fabricated at laser scribing depths of 69, 85, 119, and 127 μm varies as a function of stretching ratio. c Cyclic variation in micropillar height during ten successive cycles of release and re-stretching, corresponding to the four structures shown in (b). d Spacing of the micropillars in (b) as a function of stretching ratio. e Spacing variation of micropillars in (b) during ten cycles of release and re-stretching. Error bars represent the standard deviation of three independent measurements.
