Researchers have found an unusual 3D printable material that generates electricity in flowing water. The researchers found ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

In a development that could transform how scientists study cancer, neurodegeneration and inflammation, researchers have invented a new sensor that enables MRI machines to visualize molecular activity ...

Local-first wins.

Back in 2024, Renesas first released the RA0E1, an ultra-low-power Cortex-M23 MCU designed for cost-sensitive applications, followed by the RA0E2, with ...

Fermilab and CERN unveil upgraded quantum sensors to enhance particle detection for future collider experiments.

Loading cement sacks into trucks requires precise counting for traceability, yet manual methods are error-prone and often ...

If you happen to be in the market for a small artificial sun, you may be interested to know that for about $1300, you can get a tennis-ball-sized LED array that outputs 120,000 lumens.

Abstract: In this paper, a study on bearing-only localization for wideband off-grid sources is presented by employing distributed sensor array networks. First, the wideband off-grid signal models ...

Abstract: Superdirectivity enables compact arrays to achieve high directivity, but its practical implementations are highly sensitive to physical imperfections. This lack of robustness hinders the ...

Densely packed arrays of electrical components called capacitors can form a high-fidelity vibration sensor that can be worn on the skin. Seungjae Lee is in the School of Energy and Chemical ...
