For
engineers interested in working in the area of microfluidics, it is critical to
have a solid understanding of how fluid flow in microchannels and devices is
driven by pressure differences. This cutting-edge resource provides you with
that essential knowledge. Offering you comprehensive and up-to-date details on
all aspects of the subject, Pressure Driven Microfluidics presents the
basic laws of fluid flow, and goes on to describe sophisticated devices like
fluidic amplifiers and oscillators. Moreover, you get in-depth coverage of the
various principles of signal and power transformations between the fluidic form
and the mechanical, electric, thermal, acoustic, optical forms.
Additionally,
this practical reference provides you with a survey of the wide range of
microfluidics application areas, from microchemistry and biomedicine, to waste
water treatment and anti-terrorist warfare. Other key discussions include
simple components and devices; valves and amplifiers; basic microfluidic
circuits; and sensors, transducers, and actuators.
