[자성재료] 자기센서와 EAS System

소개

자기센서의 기본적인 원리에 대해 간단히 소개하였습니다. 그리고 본론으로 들어가서 도서관이나 상점에서 흔히 볼 수 있는 도난방지 시스템(EAS system)의 원리와 그에 사용되는 자성재료에 대해 조사한 자료입니다. 많은 도움이 되시길 바라겠습니다.

본문내용

* What is the sensor?
1. The word "sensor" was used for the first time in 1967.
2. The word "sensor" indicates some devices which transform some physical, chemical, biological properties into signals, mainly electrical signal.
3. It is originated from Latin language "sens(-us)" whose meaning is function and state of the five senses of man.
4. Mankind has used the sensors before there was no word which means "sensor". These are compass and thermometer. Nowaday sensors are used in most of the electronic devices and machines. For example, there are about 60 ~ 80 sensors in an automobile
