Accelerometers turn motion into measurable signals. From tilt and vibration to g-forces, they underpin countless designs. In this “Fun with Fundamentals” entry, we demystify their operation and take a ...

Abstract: We demonstrate a two-dimensional (2D) vector accelerometer based on hole-assisted three-core fiber (HATCF) cantilever with annular inertial mass block. The accelerometer is built by fixing ...

Accelerometers are integrated into phones, cars, spacecraft, medical devices and a host of other applications. But their evolution from crude mechanical instruments to today’s microelectromechanical ...

Abstract: An extrinsic three-component accelerometer based on fiber Fabry-Perot (F-P) interferometer is proposed. Unlike the traditional parallel connection, a dedicated filter is proposed to realize ...

Schematic diagrams of graphene NEMS accelerometers. a 3D schematic of the proposed graphene NEMS accelerometer. b 3D schematic of the cross-section of the graphene NEMS accelerometer. c, d Schematics ...

Back in 2020, Google kicked off a project to crowdsource signals from Android phones that an earthquake might be imminent. The system leveraged the accelerometers inside these devices to gather ...

If you’re the owner of an Android phone and live in a seismically active region, there’s a chance your phone has popped up an unusual warning. Not one that asks for permission to share personal ...

Physicists at the University of Colorado Boulder have created a groundbreaking quantum device that can measure 3D acceleration using ultracold atoms, something once thought nearly impossible. By ...

In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a ...
