Abstract
We previously constructed an accurate magnetdisplacement sensor for detection of eyelid movement, using an amorphous magnetic core multivibrator. However, some improvements in the eyelid movement sensor are necessary in order to achieve independence of the magnetization direction of the cores and a wider sight space. We therefore constructed another accurate magnet-displacement sensor for detection of eyelid movement, this time, using amorphous wire magnetoinductive (or MI) elements. The elements were formed by using tension annealed zeromagnetostrictive amorphous wires. The MI effect and the symmetrical MI characteristics of the elements are used to form thinner sensor heads having no coils and to change their inductances independent of the magnetization directions.
