Autonomous light-actuated LCE actuators
Liquid crystal elastomers (LCEs) are an interesting material for generating three-dimensional actuators, which can be triggered by light in a wavelength-selective manner. In collaboration with a chemist, I will fabricate the LCE actuator with the standard processes of microsystem technology. The aim is to create photo-actuated devices for integrated, miniaturized systems. We want to develop demonstrators, such as a tunable aperture system that automatically adjusts to the brightness of light, similar to how the mammalian iris functions.
