Microresonator Brillouin Gyroscope [PDF]
Using counter-propagating Brillouin lasers in a high-Q chip-based resonator, rotation measurement with a sensitivity of 15 degree/hour/ Hz is demonstrated. This is close to navigation grade performance and surpasses prior micro-optical systems by 40X.

Daily‐Life, Sensor‐Derived Tremor Measures Are Sensitive to Progression in Early Parkinson's Disease
Objective Sensitive outcome measures are critical for evaluating the efficacy of novel treatments for Parkinson's disease (PD). In this study, we assess the sensitivity to change of sensor‐derived daily‐life tremor measures over 2 years in unmedicated and medicated persons with early PD.

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

Toward Convenient and Accurate IMU-Based Gait Analysis
While inertial measurement unit (IMU)-based systems have shown their potential in quantifying medically significant gait parameters, it remains to be determined whether they can provide accurate and reliable parameters both across various walking ...

Absolute rotation detection by Coriolis force measurement using optomechanics
In this article, we present an application of the optomechanical cavities for absolute rotation detection. Two optomechanical cavities, one in each arm, are placed in a Michelson interferometer.
