More than 100 years since those pioneering experiments, researchers at Maastricht University Medical Center flipped the switch on Hoffmans's still-functional machine.

Successful interface design is perfect to handle the the relationship of function, emotion and gender, underlining the switch interface design to have a mutual aid on the functional role.

Optical switch is an important functional device in optical fibre communication networks, MEMS optical switch is one of the most promiseful optical switches.
