Membrane-Based Optomechanical Accelerometry

Physical Review Applied, 2023
Optomechanical accelerometers promise quantum-limited readout, high detection bandwidth, self-calibration, and radiation pressure stabilization. We present a simple, scalable platform that enables these benefits with nano-$g$ sensitivity at acoustic frequencies, based on a pair of vertically integrated Si$_3$N$_4$ membranes with different stiffnesses ...

Multicolor particle shadow accelerometry [PDF]

Measurement Science and Technology, 2015
This paper describes the extension of multicolor particle shadow velocimetry (CPSV) to the measurement of local acceleration in an Eulerian frame of reference. A validation experiment was conducted on a pendulous disk undergoing unsteady rigid body rotation.

Cervical accelerometry in preterm infants [PDF]

Developmental Medicine & Child Neurology, 2002
The objective of this study was to develop a method to use digital signal processing (DSP) technology to describe quantitatively and statistically swallow‐associated sounds in preterm infants and to use this method to analyze changes as infants mature. Twelve recordings of accelerometric and physiological data on bottle‐feeding preterm infants between ...

Concurrent validity of a developed accelerometry-based device for postural sway assessment [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2020
Postural control is one factor related to falls. Many instruments are available to objectively evaluate postural control performance. However, feasibility and applicability is limited by setting and financial restraints.
