We describe the development of a novel linear displacement sensor utilizing Giant Magnetoresistance (GMR) elements. This device is based on the division of a magnetically soft layer of a spin valve ...

This paper reports a method for micrometer-scale linear and angular displacement measurement based on a gradient grating period guided-mode resonance (GGP-GMR) filter. When the filter is mounted on a ...

Researchers have developed a highly sensitive photonic crystal biosensor with an eye-shaped design, which enables the ...
