Abstract
A device comprises: one or more cantilevered biomimetic cilia, and a liquid disposed among the one or more biomimetic cilia, wherein individual biomimetic cilia are at least partially submerged in the liquid, and wherein the biomimetic cilia are arranged for excitation into resonance, such as for mixing and pumping via the resonant behavior of the excited cilia.
Claims19
A device, comprising:
- a plurality of cantilevered silicone-polymer cilia attached to a common silicone-polymer backbone that comprises a plate defining a plurality of openings, wherein a plurality of the cantilevered silicone-polymer cilia are disposed in each opening, wherein each silicone-polymer cilium has a length that is at least 5 times greater than its width, and wherein a length of each silicone-polymer cilium is between about 100 nm and about 10 mm;
- a liquid disposed among the plurality of silicone-polymer cilia, wherein individual silicone-polymer cilia are at least partially submerged in the liquid;
- wherein the silicone-polymer cilia are arranged for excitation into resonance, and wherein the device does not include an attached actuator.
