An iris tuned by artificial muscles

Projektbild

Projektbeschreibung

Inspired by the dilator muscle structure of the human eye, we have designed a radially-contracting liquid crystal elastomer (LCE) actuator resembling a mammalian iris. Liquid crystal elastomers are a new material that is contracting muscle-like when it is heated and that is therefore often referred to as artificial muscle. In the project we oriented the LCEs in a radially symmetric magnetic field to realize a radial actuation. Integrated platinum heaters embedded in polyimide are used as reliable flexible heaters . The iris maintains its circular shape during actuation and can be held at different contraction states by voltage regulation.
