Abstract: The invention refers to a method, and to a device to produce emulsions and particle suspensions by using electro-hydrodinamic forces and microfluidics This combined use allow the production of droplets with mean diameters which may be either smaller than those obtained in conventional microfluidic devices or larger than those obtained by electrospray, bridging the gap between the two methods acting independently.

Abstract: A method for generating a stirring in a fluid microdrop, the volume of which is preferably greater than several tens of nanolitres, using an actuator device comprising a high-overtone bulk acoustic resonator HBAR having a quality factor Q of at least 100 in air and including a support which is substantially flat and coated with a layer of dielectric material. The HBAR resonator is associated with a modulatable electronic device capable of generating high-frequency waves. The method envisages depositing, on the support, a fluid microdrop, generating a sinusoidal electrical signal by controlling the modulatable electronic device at a chosen frequency, the frequency being between 100 MHz and 4 GHz, and transformation of the sinusoidal electrical signal having the chosen frequency into high-frequency acoustic waves (OA) by the HBAR resonator.

Abstract: A method and apparatus are provided for mixing highly viscous fluids to form a mixture. The mixture is created rapidly and has a high level of uniformity. The mixture is created by utilizing induced viscous fluid folding under the influence of an electric field. The electric field is introduced by connecting a nozzle dispensing the fluids in parallel to a voltage supply and grounding a collection plate located below the nozzle. When a certain voltage is applied the co-flow viscous fluids start to fold because the electric field exerts stress on the surface of the fluids, which results in changes of the geometry and dynamics of the viscous fluids. Control of the electric field provides great control over the mixture.
