Little Laser Trip Wire circuit presented here can detect movement of people or objects while passing through the laser beam and trigger security alarms as alert signals to those concerned. What is ...

Researchers transformed red marker ink into graphene-based circuits using a laser, enabling low-cost, flexible electronics on everyday surfaces like paper or cups. (Nanowerk News) It is the first case ...

Boise State University researchers have unveiled a cutting-edge approach to manufacturing flexible hybrid circuits—reducing costs, waste, and environmental impact. Their work leverages the properties ...

Most of us have Ethernet in our homes today. The real backbones of the Internet though, use no wires at all. Optical fibers carry pulses of light across the land, under the sea, and if you’re lucky, ...

If computers calculated using light instead of electrons, they’d be more energy efficient and at least a thousand times faster than they are today. Unfortunately, the optical analogs of computer ...

A while ago, [Marco] mounted a powerful laser diode to a CNC machine in an attempt to etch copper clad board and create a few PCBs. The results weren’t that great, but the technique was promising. In ...

AMES, Iowa – The researchers in Jonathan Claussen’s lab at Iowa State University (who like to call themselves nanoengineers) have been looking for ways to use graphene and its amazing properties in ...
