Liquid Crystal Oscillators
Previously, we have made liquid crystal fibers that can bend when locally heated. Recently, a new method has allowed for the creation of liquid crystal fibers with conical heads. When heated, these cones deform in a complex way, which allows for their use as switchable suction cups
While the fibers can be controllably bent via computer-controlled contact heating, an elegant way to deform the cones does not yet exist. One option is to include a dye in the fiber to allow for photothermal actuation, while another option is to change the liquid crystals used to allow for photomechanical actuation. Finally, it will be necessary to integrate the light source and -control with the fibers to create a functional device.
