Abstract
The invention relates to measuring devices used for measuring angular velocity, and more precisely, to vibrating micro-mechanical sensors of angular velocity. The sensor of angular velocity according to the invention comprises at least two seismic mass structures (), (), excitation structures (), () and coupling seesaw type springs (), (). The objective of the invention is to provide an improved sensor structure, which enables reliable measuring with good efficiency particularly in small vibrating micro-mechanical angular velocity sensor solutions.
