Molecular Electronic Angular Motion Transducer Broad Band Self-Noise

Abstract: Modern molecular electronic transfer (MET) angular motion sensors combine high technical characteristics with low cost. Self-noise is one of the key characteristics which determine applications for MET sensors. However, until the present there has not been a model describing the sensor noise in the complete operating frequency range. The present work reports the results of an experimental study of the self-noise level of such sensors in the frequency range of 0.01–200 Hz. Based on the experimental data, a theo… Show more

“…This noise is generated from hydrodynamic fluctuation of the electrolyte through the electrochemical MET cell. From Safonov (2003) and Zaitsev et al (2015) we know that there is another noise type connected to arising of the close vortex in the channel. This noise is called geometrical and is given by the formula…”

“…where α is the dimensionless empirical coefficient, which characterizes scatter of the transfer function for different micro-channels of the electrochemical MET cell. Numerical value α = 0.31 is calculated in Zaitsev (2015). Moreover, there is noise described in Safonov (2003) that is generated from convection.…”
