Reliability of Self-Applied Smartphone Mechanocardiography for Atrial Fibrillation Detection

open access: yesIEEE Access, 2019
Smartphone mechanocardiography (sMCG) is a new technique that allows patients to record a cardiac rhythm strip using a smartphone built-in tri-axial accelerometer and gyroscope.

A Large Area Fiber Optic Gyroscope on multiplexed fiber network [PDF]

open access: yes, 2013
We describe a fiber optical gyroscope based on the Sagnac effect realized on a multiplexed telecom fiber network. Our loop encloses an area of 20 km2 and coexists with Internet data traffic.

Anti-parity-time-symmetric integrated optical gyroscopes

open access: yes, 2021
Parity-time-symmetric optical gyroscopes are gaining interest for the enhanced sensitivity shown by exceptional points. The real splitting of anti-PT-symmetric gyroscopes is more reliable for stability and readout scheme than the complex splitting of ...

Sagnac Gyroscopes and the GINGER Project

open access: yesFrontiers in Astronomy and Space Sciences, 2020
Large-frame optical Sagnac gyroscopes, more commonly called ring laser gyroscopes, are considered the only device able to provide fast and very high sensitivity measurement of the length of the day (LOD) and of the Earth rotation axis variations. Several

Eigenmode operation of piezoelectric resonant gyroscopes

open access: yesMicrosystems & Nanoengineering, 2020
The theory of eigenmode operation of Coriolis vibratory gyroscopes and its implementation on a thin-film piezoelectric gyroscope is presented. It is shown analytically that the modal alignment of resonant gyroscopes can be achieved by applying a rotation

Analysis of ring laser gyroscopes including laser dynamics [PDF]

open access: yesThe European Physical Journal C, 2019
Inertial sensors are important at application level and also in fundamental physics. Ring laser gyroscopes, which measure angular rotation rates, are among the most sensitive ones.
