fluidische

Fluidische refers to fluidics, the engineering discipline that studies and applies the control of liquids and gases. In German-speaking contexts, fluidik or fluidische covers systems that route, regulate, and convert fluid energy, often emphasizing compact, robust control with few moving parts.

Key principles include the Navier–Stokes and continuity equations, laminar versus turbulent flow, Reynolds number, and surface/interfacial phenomena such as capillarity. At micro- and nano-scales, flows are typically laminar and mixing relies on diffusion, enabling precise handling of small fluid volumes.

Devices and technologies include microfluidic channels and chips, valves and pumps (pneumatic, electrokinetic, or capillary-driven), droplet generators, mixers, and digital microfluidics based on electrowetting. Fluidic logic—using fluid jets and exhausts—has historically enabled computation without moving solid parts.

Applications span laboratory automation, chemical analysis, medical diagnostics, point-of-care testing, environmental monitoring, and pharmaceutical screening. Fluidische approaches prioritize low sample consumption, integration with sensors, biocompatibility, and scalable fabrication.

History and scope: Fluidics emerged in mid-20th-century research on fluidic amplifiers and logic, evolving with microfabrication to form modern microfluidics. Today, fluidische concepts appear across science and industry, linking physics, engineering, and biology to enable compact analytical systems and automated fluid handling.
