Sensors help microprocessor-based systems find their bearings. Where would embedded systems be without them? Sensors provide the windows through which microprocessor-based systems can observe their ...

Researchers have developed a fast and accurate flexible tactile optical sensor capable of reading Braille. The technology could enable smart readers that convert Braille to speech or text, helping to ...

The Optipact motion sensors determine rotational or translational velocities of machinery or products in a wide variety of applications. The sensors are built around an optical system: The velocity of ...

I am always on the lookout for ideas for simple test and measurement instruments that can be used on my workbench. Over the years, I have built dozens of little test instruments and home lab ...

Aging degradation and seismic damage of civil infrastructure pose a serious problem for society. One promising technology for monitoring the condition of structures is optical fiber sensing. By ...

Fiber-optic sensors work well in tight spots and in applications with a high degree of electrical noise, but care must be taken when specifying these critical components. Sensing part presence in ...

Analog and digital optoelectronic sensors combine an LED and an optoelectronic integrated circuit in a compact package to enable optical encoders to provide absolute or incremental position detection ...
