As part of a project demonstrating new 3-D printing techniques, Princeton researchers have embedded tiny light-emitting diodes into a standard contact lens, allowing the device to project beams of ...

Researchers at MIT have unexpectedly stumbled upon a way to 3D print active electronics – meaning transistors and components for controlling electrical signals – without the use of semiconductors or ...

Researchers produced 3D-printed, semiconductor-free logic gates, which perform computations in active electronic devices. As they don't require semiconductor materials, they represent a step toward 3D ...

A variety of linear models are available to represent common active electronic devices such as transistors and vacuum tubes. Devices operating under large-signal conditions often require nonlinear ...

Researchers from the Massachusetts Institute of Technology have demonstrated fully 3D-printed resettable fuses, essential components in active electronics that usually rely on semiconductors. However, ...

I know, I know—discussing the subject of a relay-based sequence switch in the age of omnipresent microprocessors seems to be a waste of time. After all, relays have been in use for many years. Is it ...

(Nanowerk News) Active electronics — components that can control electrical signals — usually contain semiconductor devices that receive, store, and process information. These components, which must ...
