HORSEHEADS, N.Y.--(BUSINESS WIRE)--Our nation’s utilities are at a critical crossroads in the transmission, distribution, and generation of electricity. Renewable integration, power quality issues, ...

Using their Mosquito fabrication method, the researchers created a fan-out pattern of multiple thin light paths inside a thin sheet of PDMS. This created four optical channels that could be used for ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

There is a point where taking technology for granted hides some of the incredible capabilities of seemingly simple devices. Optical mice are a great example of this principle, using what are more or ...

Leuze has introduced a broad range of stainless steel optical detectors for the food industry. “The devices are designed for reliable operation in wet areas and during intensive cleaning processes and ...

Carbon nanotube: these structures have been used to create a new and flexible light sensor. (Courtesy: iStock/theasis) A flexible, ultrathin optical sensor that uses carbon nanotubes to convert light ...

Satellite-based electro-optical sensors are intended to detect missile launches early on, gaining valuable time for initiating countermeasures in case of an attack. The Fraunhofer Institute of ...

For decades, people with diabetes have relied on finger pricks to withdraw blood or adhesive microneedles to measure and manage their glucose levels. In addition to being painful, these methods can ...
