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 micropump ....etc

Dr.Y.NARASIMHA MURTHY Ph.D [email protected] Sensors and Interfacing techniquesIntroductionSensors are sophisticated devices which will detect and measure any non-electrical physicalquantity .A Sensor converts the physical parameter (for example: temperature, blood pressure,humidity, speed, etc.) into a signal which can be measured electrically.Sensor is sometimes called a primary measuring element, which can be found simply as amercury thermometer to measure the temperature. It may be embedded in the transducer toperform its function. That m ....etc

Nanorobotics
Definition

Nanorobotics is an emerging field that deals with the controlled manipulation of objects with nanometer-scale dimensions. Typically, an atom has a diameter of a few ?ngstroms (1 ? = 0.1 nm = 10-10 m), a molecule's size is a few nm, and clusters or nanoparticles formed by hundreds or thousands of atoms have sizes of tens of nm. Therefore, Nanorobotics is concerned with interactions with atomic- and molecular-sized objects-and is sometimes called Molecular Robotics.

Molecular Robotics falls within the purview of Na ....etc

The OMEGA OS35 Series Infrared Temperature Sensors provide intelligence in a robust, easy-to-use package. The OS35 is centered around a high-speed microprocessor that continuously monitors and adjusts the entire system. By performing the complex algorithms that determine the output, it is also calibrated approximately once every second, eliminating any concerns about drift or sudden changes. Other advanced features include emissivity offset compensation and ambient radiation error correction. Rugged housing withstands thermal and mechanical sho ....etc

Instrumentation that converts the signal to engineering units must know a few things about what parameters to expect from the sensor. That's because full-scale range, sensitivity, connection schemes, and other factors all vary greatly from one kind of sensor to another. The end result is that it takes some effort to match up sensors with monitoring electronics. This configuration process may be no big deal when there are only a few sensors involved. But it can be problematic when gangs of sensors get wired into multichannel measurement systems. ....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.
