Abstract:
The present invention relates to an improved valveless micropump with dome shaped dielectric elastomer diaphragm, pumping chamber and nozzle diffuser as flow control element. More particularly, the invention relates to a valveless diffuser type reciprocating displacement pump for delivering fluid in microlevel for various applications like drug delivery system, chip cooling, micro-propulsion, chemical delivery. It can also be used in the field of chemical dosing to deliver drop wise pulsed fluid, as it can work at low frequency also. Present invention is a low cost easily fabricated high as well as low flow rate micro- machined micropump. Due to absence of moving parts, the performance of the pump improves and clogging of micropump has also been eliminated.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
