Acoustoelectric transducer based on electrokinetic phenomenon flow potential

نویسندگان

چکیده

A mathematical model of an acoustoelectric transducer based on the use electrokinetic phenomenon flow potential is proposed. It shown theoretically that increases in proportion to strength constant electric pumping field, which confirmed experimentally. The described converter has variable sensitivity. Rather large values sensitivity microphone have been obtained results work can be used design transducers. Keywords: Acoustoelectric conversion, Electrokinetic phenomena, Current potential, Flow hydrodynamics, Energy pumping.

Microfluidic flow transducer based on the measurement of electrical admittance.

A new flow transducer for measuring the flow rate of a conducting fluid in a microchannel is reported. In this paper, the measure of flow of such fluid under laminar flow conditions based on the change of electrical admittance is established with the aid of a pair of electrodes parallel to the line of flow in a glass-PDMS microfluidic device. This flow sensor is simple in design and can be inte...

Electrokinetic Flow Diagnostics

S. Devasenathipathy and J.G. Santiago The advent of microfabricated chemical analysis systems has led to a growing interest in microfabricated fluidic systems with characteristic scales in the range of a micron to a millimeter. A motivation to integrate components in a manner analogous to modern microelectronics is coupled with a potential for achieving massively parallel functions, and the fie...

Two-fluid Electrokinetic Flow in a Circular Microchannel (RESEARCH NOTE)

The two-fluid flow is produced by the combined effects of electroosmotic force in a conducting liquid and pressure gradient force in a non-conducting liquid. The Poisson-Boltzmann and Navier-Stokes equations are solved analytically; and the effects of governing parameters are examined. Poiseuille number increases with increasing the parameters involved. In the absence of pressure gradient, the ...

Numeric simulation of heat transfer and electrokinetic flow in an electroosmosis-based continuous flow PCR chip.

Precise design and operational control of the polymerase chain reaction process is key to the performance of on-chip DNA analysis. This research is dedicated to understanding the fluid flow and heat transfer mechanisms occurring in continuous flow PCR chips from the engineering point of view. In this work, a 3-dimensional model was developed to simulate the electrical potential field, the flow ...

Electrokinetic Flow and Dispersion in Capillary Electrophoresis

Electrophoretic separation of a mixture of chemical species is a fundamental technique of great usefulness in biology, health care, and forensics. In capillary electrophoresis (which has evolved from its predecessor, slab-gel electrophoresis), the sample migrates through a single microcapillary instead of through the network of pores in a gel. A fundamental design problem is to minimize dispers...
