Abstract: Fluidics is a new technology arising from a re-appraisal of a very old technology, namely fluid power and its control. Fluidic technology based on natural oscillation phenomena is a relevant topic in several strategic areas. This technology of using the flow characteristics of liquids or gases to operate a control system is fairly old; it was in the 1960s that researchers started to use fluidics. Important contributions from fluidic logic technologies are associated with the fluid behavior known as the “Coanda effect”. A lot of attention has been paid to the transport phenomena in the micro geometries because micro fabrication enables us to manufacture low channels ranging from few micrometers to few hundred micrometers. This paper describes a new actuator for flow control applications. The gas diffusion, control is very important operation in the fields of nature and industry.

Keywords: Fluidic, Microfluidic, Amplifiers, Oscillators, Gas flow
