Abstract
This presentation describes a new valveless micropump for bidirectional use. The micropump was fabricated by bonding a fluidic channel and a membrane actuator. The fluidic channel was etched on a glass substrate and the membrane actuator was made on a silicon wafer. The membrane is actuated by a piezoelectric ceramic (PZT) plate so that the membrane generates blowing and suction flows successively along an oblique channel which is connected to the main channel. A blowing flow from an oblique channel into the ma ....etc

ABSTRACT
The conventional modes of pumping are centrifugal, reciprocating, gear pump, lobe pump, vane pump etc. But these types of pumping cannot be used in delicate areas such as medical field, labs, pumping different types of fluids etc. Bec ....etc

Introduction
A number of different micropumps have been developed over the last decades. Among the various kinds of working principles, the micropump using membrane actuation is known as a promising approach. Therefore, a lot of membrane micropumps have been studied with various actuators. The valve is another issue for the development of micropumps. Since a piezoelectric micropump with check valves was first presented by Van Lintel et al. , passive or active check valves have been widely used for micropumps. The micropump with check valves ....etc

Microfabrication technology has been successful in producing a wide range of miniature sensors and mechanical devices. Of particular interest is the application of this technology to biological systems. For instance an immunobiosensor for a bacterial food toxin with a sensitivity of 1 ng/mL and miniature reaction chambers have been fabricated for DNA analysis sequencing by hybridization. The integration of sensors with other components, particularly fluidic devices, offers the promise of microsystems. A miniature positive displacement micropum ....etc

Micropumps




ABSTRACT
If a high and on-going research dynamics is taken as a rejuvenating factor, microfluidics can still be regarded as a truly young discipline, although some microfluidic devices definitely can not be considered as “youngsters” any more. In a time of 30 years of ISFETOLOGY it may be worth to take a look at these devices in order to examine, whether they had – and still have – the potential to stimulate the imagination and creativity of researchers in a similar way as the Io ....etc

MADICINE BY MICROMACHINE
ABSTRACT
The bedrock of modern medicine is an age-old technology: the pill. For the most part, it works. The drug inside the pill finds its way to whatever part of the body it's meant to treat, and the patient recovers.
But sometimes, oral medications just aren't effective. The medication may interact with other drugs or food. It may break down in the stomach before entering the bloodstream. Or, even more frightening, it may trigger other, bigger problems even as it aims to cure. Recall the painkiller Vioxx, which di ....etc

ABSTRACT
In todayâ„¢s fast world, man is in a situation where he has to compete against machines. Due to this stress of a mechanical life, the human body is subjected to various levels of trauma. The organ most affected is the heart. Heart attacks are becoming so common now a day. The percentage of people affected is increasing by the day. This heart attack is mainly caused due to improper diet with excessive cholesterols and l ....etc
