Moving from Electromechanical to Solid-State in Relays and Circuit Breakers

By Giovanbattista Mattiussi, Product Marketing Manager, Infineon Technologies

As a mature technology, electromechanical relays and circuit breakers are well established, however they continue to suffer from some inherent weaknesses. Moving to solid-state technology can address these but introduces its own challenges. So, what is the right solution? In the movies, whenever the lights go

Squid-Inspired Robots Might Have Environmental Applications

American Institute of Physics

WASHINGTON, D.C. -- Inspired by the unique and efficient swimming strategy of cephalopods, scientists developed an aquatic robot that mimics their form of propulsion. These high-speed, squidlike robots are made of smart materials, which make them hard to detect -- an advantage that has potential military reconnais
