Design, Fabrication and Characterization Amorphous Silicon-Based Electromagnetic Sensor

Abstract

A strong demand of the commercial market for reliable, high performance and low cost sensors leads to the need of developing new technology. In this project, electromagnetic sensors with small size are produced utilizing UniMAP facilities. The reduction in sensor size can avoid of excessively consuming the material and make easy to intergrate the sensors into a circuit. This is an effective way to realize the sensor production, operation and maintenance with low cost. In this project, electromagnetic sensors having a transmitter and a receiver in parallel position have been designed, fabricated and charaterized. The change in the magnitude of magnetic field when a conductive material passes through the magnetic flux lines between the transmitter and receiver is investigated. The electromagnetic characteristics measured are related to the microstructure.
