Due to their small size, micro-sensors experience complex phenomena which affect their intrinsic properties, with in particular nonlinear anomalies. These features dramatically change the measured outputs of micro-sensors and decrease their performance. In the case of micro gyroscopes, nonlinearity can be a source of angle-dependent bias error coming from both the involved dynamics of the system and from measurement alterations. However, a careful control of these nonlinearities opens the way for new implementation schemes and higher sensitivities in micro sensors. This project involves both experimental and theoretical approaches to study the effect of nonlinearity on the operating modes used in micro gyroscopes, with the aim of using these nonlinear behaviors in order to increase the current performance of those micro-sensors.
