Researchers unveiled SOLen, a 3D printed soft optical sensor that guides light with an internal lens for mechanosensing.

In a multi-year project, researchers at Chalmers University of Technology in Sweden have developed plasmonic plastic – a type of composite material with unique optical properties that can be ...

As desktop 3D printers have inched towards something resembling the mainstream, manufacturers have upped their game across the board. Even the quality of filament that you can get today is far better ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...

Interest in plasmonic metal nanoparticles and their many different applications has grown rapidly, developing across a broad spectrum over the past two decades. What makes these particles so special ...
