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 ...

Targeting use in tablet computers, notebooks, and smartphones, the CM36262 optical-lid-sensor chip contains a patent-pending optical-lid sensor, an ambient-light sensor, and a proximity sensor. The ...

Cells are squishy and soft. Tiny nanometer-sized particles such as quantum sensors cannot move freely inside them due to viscous drag, which makes sensing challenging. Researchers at the Indian ...

Nanodiamond quantum sensors mounted on magnetic microbots achieve coherent spin control while moving freely through fluid, a ...

Physicists have engineered light to drift sideways in discrete, quantized steps inside a fiber-optic loop, reproducing a signature behavior of the quantum Hall effect without electrons, magnetic ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...

Add Yahoo as a preferred source to see more of our stories on Google. In interesting research, insights from ordinary supermarket grapes led researchers to boost quantum sensor performance. The study ...

Physicists have unveiled a breakthrough in quantum sensing by demonstrating a 2D material as a versatile platform for next-generation nanoscale vectorial magnetometry. A team of physicists at the ...

In any application using motors for automation, there is a need to ensure accurate control of the motor. To make this possible, the position and speed of the rotor in the motor, which is usually ...

The magnetic sense of migratory birds such as European robins is thought to be based on a specific light-sensitive protein in the eye. Researchers demonstrate that the protein cryptochrome 4, found in ...
