The motivation for this project comes from the fact that one of group members, Marc S. Hernandez, is colorblind. A need was realized for a device to assist people with their color perception ...

Abstract—Reflective color sensing is typically realized through pho- todiodes with multiple illuminants or photodiodes coated with color filters containing a single illuminant. This paper presents the ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an ...

An inexpensive detector developed by a NASA-led team can now see invisible infrared light in a range of “colors,” or wavelengths. The detector, called a Quantum Well Infrared Photodetector (QWIP) ...

Scientists have developed a dye process that helps detect wear-and-tear on electric motor wire insulation. Typically, engineers can tell the condition of an electric motor by the wear on the ...

Xinjian Zhou and colleagues from Sandia National Laboratories took single-walled carbon nanotubes and functionalized them with azobenzene chromophores to create molecularly engineered photosensitive ...

Environmental contaminants like fluoride, lead, and pesticides exist all around and even within us. While researchers have simple ways to measure concentrations of such contaminants inside lab ...

A team of researchers has developed a new biosensor that turns the invisible signals into visible color changes to detect urea levels in a simple way. The sensor works by combining gold nanoparticles ...

A quick and simple fluorescent test can detect trace quantities of benzene in both liquid and vapor form. The new test uses paper strips impregnated with a supramolecular host-guest assembly system ...

A new fiber-optic sensor made from stretchy rubber rather than glass can be integrated into wearable electronics and measure movement. The sensors can also quantify the force of stretching, bending, ...
