GMR sensors

Introduction
GMR - Giant Magnetoresistance
Discovered in the late 1980s
Very large resistance changes in materials with magnetic field
The GMR effect states significant decrease in electrical resistance in the presence of a magnetic field.
Size of magnetic field is 10-100 Oe

Features
High sensitivity for low magnetic fields
Measures field parallel to its sensitive axis
Good signal-to-noise ratio
High spatial resolution
Frequency independent sensitivity
Low cost, Less p ....etc

Abstract—Radio Frequency Identification (RFID) has been developed as an important technique for many high security and high integrity settings. In this paper, we study survivability issues for RFID. We first present an RFID survivability experiment to define a foundation to measure the degree of survivability of an RFID system under varying attacks. Then we model a series of malicious scenarios using stochastic process algebras and study the different effects of those attacks on the ability of the RFID system to provide critical services even ....etc

Abstract
The channel bridging, signal regenerating, andfunctional rebuilding of injured nerves is one of the mostimportant issues in life science research. In recent years, someprogresses in the research area have been made in repairinginjured nerves with microelectronic neural bridge. Based on theprevious work, this paper presents a neural signal detection andfunctional electrical stimulation (FES) driving system with usinghigh performance operational amplifiers, which has been realized.The experimental results show that the designed ....etc

SEMIANR REPORT ON Giant Magnetoresistance Effect



ABSTRACT
The Giant Magnetoresistance Effect was discovered in 1988. It took around 10 years of laborious research for its first fruits to be ripened. But once they were on, they started to cause unprecedented increase in the storage capacity of hard disks. Another area of application is the primary memory. The seminar presents the details of this discovery and the impact it had on the industry. ....etc
