Abstract: Production and the distribution of pico and nano-drops, which are extracted by the effect of a strong electric field generated by pyroelectric effect, in particular, but not exclusively, from a sessile drop (a drop placed on a surface assumes a form termed “sessile”) or by a liquid film, and distributed on a dielectric substrate. The electric field is advantageously generated applying a heat source on the dielectric substrate or utilizing a laser source emitting in the infrared region. In this new approach, it is not necessary to use fixed electrodes, circuits, high tension generators or to design intentionally, and therefore to realize, pico- and nano-nozzles.

Abstract: A liquid crystal elastomer actuator to move in a fluid is described herein. The actuator includes a body with dimensions between 100 nm and 800 ?m having a low Reynolds number. The body includes a first and a second spatially separated volume, each comprising a liquid crystal elastomer. The first volume is doped with a first photoactive doping substance to absorb electromagnetic radiation at a first wavelength and the second volume is doped with a second photoactive doping substance to absorb electromagnetic radiation at a second wavelength. The first and second volumes change shape as a consequence of light absorption at the first or second wavelength, defining a first and a second joint. A first absorbance of the first volume at a given wavelength is different than a second absorbance of the second volume at a given wavelength, the first and second absorbance are measured in the same time interval.
