Giant magnetoresistance (GMR) sensor has been developed and widely applied to use as magnetic read head in data storage industry. This paper describes new applications of magnetic-field measurement with high spatial-resolution and high sensitivity to nondestructive evaluation and biomedical engineering. For nondestructive evaluation, the GMR sensor, used as magnetic sensor based on eddy-current...
Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor. SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...

Decreasing the dimensions of ionic conductors to the nanoscale has enabled the realization of new electrochemical devices integrated on Si-based and other microsystems. These comprise fast ionic conducting electrolytes for energy-applications such as micro-fuel cells [ 1,2 ] and batteries, [ 3 ] gas conversion/reformation catalysts, [ 4,5 ] sensors, [ 6 ] and for redox-reaction based resistive ...
Power measurement systems, such as Phasor Measurement Unit (PMU) structures, require installation of special voltage and current instrument transformers connected to the energized conductor to collect data from the power line. While non-contacting methods of current monitoring are already well known and implemented, the contactless voltage monitoring is still lacking. This paper describes a tun...
A dissolved methane sensor based on silicone tube was designed, constructed and optimized.The silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.A continuous stream of helium (50 mL/min) was directed through the tubing, sweeping out the...
This paper presents Density Functional Theory and Non-Equilibrium Green’s Function based First Principles calculations to explore the sensing property of Adenine and Thymine based hetero-junction chins for Ammonia and Phosphine gas molecules. This modeling and simulation technique plays an important and crucial role in the fast growing semiconductor based nanotechnology field. The hetero-juncti...
We demonstrate the feasibility of using novel, small energy harvesters to power atmospheric sensors and radios simply attached to a single conductor of existing overhead power distribution lines. We demonstrate the ability to harvest the required power for operating multiple atmospheric and power-system sensors, together with short-range radios that could broadcast atmospheric sensor data to th...
