Sensors

Imagine a body sensor powered by one's jewelry, or a cooking pan that charges a cell phone in a few hours. Using a combination of the chemical elements calcium, cobalt, and terbium, University of Utah researchers created an efficient, inexpensive and bio-friendly material that...

Researchers from the National Institute of Standards and Technology (NIST) have developed a way to embed a nanoscale damage-sensing probe into a lightweight composite made of epoxy and silk.

This week's Question: Toymaker Mattel recently announced the introduction of a smart baby monitor; The voice-controlled "Aristotle" uses artificial intelligence (AI) to automate functions like changing lights, playing lullabies, or triggering white noise. With an estimated 25...

Quality measurements for design validation and certification requirements sometimes call for hundreds or thousands of sensors and actuators. Maintaining such a complex system is difficult, especially over an extended time period and inevitable personnel changes. Many...

NASA Langley Research Center researchers have developed a wireless, low-profile sensor that uses a magnetic field response measurement acquisition system to provide power to the sensor and to acquire physical property measurements from it. Unique to...

This year's Consumer Electronics Show (CES) in Las Vegas showcased many new consumer products featuring voice control. LG, for example, introduced a smart refrigerator equipped with Amazon's Alexa voice service. Other CES technologies with voice-recognition capabilities included...

NASA’s Jet Propulsion Laboratory offers a method to manufacture biomarker sensor arrays with nanoscale resolution and active regions on the order of 1 micron by applying nanolithographic direct-write techniques to the fabrication of Silane...

The use of thin-film sensors has several advantages over wire or foil sensors. For example, thin-film sensors do not require special machining of the components on which they are mounted, and, with thicknesses less than 10 μm, they are considerably thinner than wires or...
