Fig. 4: Complex actuation manners of LCEs.
From: Programming actuation onset of a liquid crystalline elastomer via isomerization of network topology
a Active LCE strip with two distinct TNI patterned via UV exposure exhibits a sequential actuation. b Reversible multi-shape actuation. The white areas are exposed to UV light for 2 min. Square size: 1 mm × 1 mm. c, d Self-locked and self-correctable actuation behavior of the four-leaf clovers with single and quadri TNIs. The number in each petal indicates the irradiation time (s). Scale bar: 1 cm.
