Latest Patents

Etienne Herth holds a patent titled "Method for generating a flow in a microdrop and device for implementing the method." This invention describes a method for creating stirring in a fluid microdrop, which is typically greater than several tens of nanoliters. The method utilizes an actuator device that includes a high-overtone bulk acoustic resonator (HBAR) with a quality factor Q of at least 100 in air. The HBAR resonator is paired with a modulatable electronic device capable of generating high-frequency waves. The process involves depositing a fluid microdrop on a flat support coated with a dielectric material, generating a sinusoidal electrical signal at a frequency between 100 MHz and 4 GHz, and transforming this signal into high-frequency acoustic waves by the HBAR resonator.
