Development of Liquid Crystalline Elastomers as Soft Mechanical Actuators
… First, the external stimuli to trigger LCE actuation is demanding (i.e., stimuli can be difficult to deliver). Second, less desirable properties of the LCE limit their deployment (i.e., diminishing mechanical properties during their actuation). Third, industries simply need to take time to …

Microscale actuators from carbon nanotube and hydrogel composites
… have sizes ranging from 10 µm to 1 mm respond to light, can be cycled over 1500 times with no sign of degradation, and have response times as fast as 15 ms. The driving force for the actuators is the volume phase transition of PNIPAM. PNIPAM is a lower critical solution temperature (LCST) polymer …
