A study on mass microsensors using Anderson localization is conducted in this thesis. Different ways allowing to enhance their performances are proposed and demonstrated through two MEMS devices. Both devices use the same system composed of two mechanically coupled cantilevers, but the vibrations are generated in two different ways: the first device is actuated with an attractive electrostatic force while the second device is actuated with a repulsive electrostatic force. In order to get rid of initial imbalance due to manufacturing defects, the electrostatic softening effect is used by tuning the DC voltage of the actuation. For the first device, a concept with an asymmetric system including two cantilevers of different lengths is proposed. We thus reduce the effective stiffness of the short cantilever to balance the system. With the second type of actuation, the weak electrostatic softening effect forces us to use two microbeams of the same length. But the system is still balanced with the same approach. Thanks to the functionalization of electrostatic nonlinearities, the first device shows an enhanced sensitivity, which is 67% higher than the maximum sensitivity reachable in the linear regime. Concerning the second device, it shows the absence of electrostatic nonlinearities, which allows to increase the linear dynamic range by up to 70% of the gap. It should improve not only the mass resolution of the sensor, but also the accuracy of the mass sensing. All of these concepts are first theoretically investigated with the developed analytical model based on the Euler-Bernoulli beam theory. They are then experimentally demonstrated after the sensors are manufactured with the MUMPS

Direct detection of Gravitational Waves was demonstrated for the first time in 2015 with km-scale Michelson interferometers. In order to reduce the shot noise at high frequency of these detectors high optical power in the arm cavities is needed. At that high circulating power a nonlinear optomechanical phenomenon called parametric instability (PI) may occur that induce the amplification of mirror’s eigenmodes. It limits the optical power and can cause the loss of the interferometer’s control if notmitigated.Several PI mitigation strategies have been proposed and already implemented in current gravitational wave detectors. These schemes keep them working without PI at the current optical power level in the cavities but they are not adapted to PI involving any kind of mechanical mirror modes, which needs to be considered when the optical circulation power is increased further. Next generation detectors aim at increasing their sensitivity of a factor of ten compared to current detectors. This can be achieved, inter alia, through the increase of the optical power in the arm cavities which will imply more PI.In this thesis an active and flexible PI mitigation strategy based on radiation pressure of a movable laser beam is proposed. The idea is to apply a damping force to mitigate PI. Fast beam steering is required to point at different positions of the cavity mirror with a small laser spot during one period of the mechanical mode with frequencies in the kHz-range. A sensitive sensing method is required to detect PI at the level ofthermal excitation.First experimental studies of a table-top setup are presented: rapid beam deflection based on acousto-optic modulators is investigated. A final configuration with 2D arbitrary beam steering with a maximal deflection rate of 10 MHz is demonstrated for a maximal optical power of 3.6 W, corresponding to a radiation pressure force of 24 nN. It satisfies the requirements of the laser beam that should be used as radiation pressure force for our proposed PI damping scheme.Sensing of mechanical mirror modes is investigated with the 2D beam steering system based on a Michelson interferometer. A sensitivity corresponding to a differential arm length change of δL = 4.8 · 10^-14 m/√Hz is achieved for a fixed beam position on the mirror. It is around one order of magnitude higher than the expected displacement of the mirror due to thermally excited mirror modes. Propositions are given to improve the sensitivity of the interferometer and to use the same setup to investigate active damping of mirror modes via radiation pressure

Vibration analysis is mainly used in condition monitoring and fault detection of rotating machine domain. The success of the diagnosis is strongly related to the position of the accelerometers. However, the machine geometry sometimes prevents the sensors to be placed close enough to the faulted part causing the diagnostic failure. The sound emitted by a mechanism and its condition are related. Using microphones to optimize condition monitoring is then justified. Acoustic imaging techniques (acoustic holography, beamforming, etc…) are mainly used as a source localization and quantification tool but they can be turned into a powerful diagnosis tool. Several strategies based on the beamforming algorithm are developed in this work. Firstly, diagnosis features commonly used in condition monitoring of rotating machinery are mapped as a function of space. Kurtosis allows localizing impulsive sources which eventually can be related to a mechanism failure. New features based on the squared envelope spectrum of the focused signals are also introduced. They aim toward the detection of inner and outer race fault in roller element bearings. On the other hand, angular synchronous average is used to extract the acoustic field synchronous with one component rotation. The sources related to a fault are localized in the residual field mappings. Finally, a new imaging technique based on the vibroacoustic transfer functions between a few accelerometers placed on the machine and the microphone array is developed. It allows obtaining the mappings of the radiated pressure on the machine surface only thanks to the accelerometers. It is tested as a fault detection tool on a test bench
