Cellophane Flyer Powered By Microwaves

Another insect inspired flying robot. This time the wings are made from a thin sheet of cellophane rather than polysilicon.
When the wings are energized with microwaves they can flap like butterfly wings.
The cellophane is cellulose - the building block of plants - dissolved in a xanthate solution and dried into a film. Very common stuff. Once plated with gold it becomes Electroactive paper, EAPap.

The paper can be shaped into wings with an integrated antenna so that they can be powered and driven with only microwaves.
