Abstract:-
Our varying industrial needs demand more precise control of the outputs of our basic electrical prime movers i.e, THE MOTORS. Basically dc motors are easy to control compared to their ac counter parts, but they have their own limitations with increase in capacity. Conversely ac motors in particular squirrel cag ....etc

Wearable sensors and systems have evolved to the point that they can be considered ready for clinical application. The use of wearable monitoring devices that allow continuous or intermittent monitoring of physiological signals is critical for the advancement of both the diagnosis as well as treatment of diseases. Wearable systems are totally non-obtrusive devices that allow physicians to overcome the limitations of ambulatory technology and provide a response to the need for monitoring individuals over weeks or months.

Abstract
In this paper, the current version of the artificial retina prosthesis and cortical implant that is being developed will be described. A multi disciplinary team of researchers in Ophthalmology, Neurosurgery, Computer Networking, VLSI, and Sensors has been assembled to develop the novel solutions needed to make artificial vision for the visually impaired a reality. This paper describes the novel approach that has been adopted for providing a complete system for restoring vision to visually
Impaired persons ....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

The interface between different fields is believed to be fertile ground for breakthrough research. The interface between the emerging fields of biotechnology and nanotechnology is particularly interesting. The possibilities for new fruit are diverse: biotechnology offers new approaches for self-assembly of structures at the nanoscale, while nanotechnology offers new methods for probing and accessing biological systems. In this talk, I will discuss research in this new frontier in my group, including 1) self-assembly of 2D nanocomponent arrays ....etc
