AlGaN/GaN heterostructures are unique because the 2DEG at the interface is created by the difference in polarization properties of the AlGaN and the GaN layers; not due to intentional doping. In this work, a 3D model of an electrostatically actuated micro cantilever has been developed ... Per saperne di più
Functionally graded materials (FGM) are those that contain chemical, phase or structural gradients. Whilst the design of functionally graded structures is well researched in areas such as shape optimisation and topology optimization, their manufacture is still in development. One ...

Micromachined ultrasound transducers can work as a sensor or actuator for measuring fluid speed and direction, mixing and exciting particles (sonication), taking images (ultrasonography), non-destructive testing and many other purposes in various fields. In this work, a COMSOL ... Per saperne di più
The shear mode of film bulk acoustic resonators (FBARs) is preferred to the longitudinal mode owing to its lower acoustic losses in a liquid. However in addition to mass loading, the resonance is also affected by temperature and liquid viscosity. These two parameters can either be sensed ... Per saperne di più
Optical tweezers work on the idea of non-contact Optical Pressure felt by transparent particles, when shined by coherent light source such as lasers. On the other hand when light falls on the metal it excites the electron inside it and make them free. When these free electron cloud ... Per saperne di più
This paper presents ongoing research aimed at development of a MEMS magnetometer capable of nanoTesla sensitivity. Such a device would pave the way for inertial-grade MEMS IMUs. A resonant sensor is proposed, based on a Xylophone Bar sense element, and is analysed both directly and via ... Per saperne di più
Microelectromechanical systems (MEMS) are becoming more prevalent in today’s space technologies. The Visible Nulling Coronagraph (VNC) instrument, being developed at the NASA Goddard Space Flight Center, uses a MEMS Mirror to correct wavefront errors. This MEMS, the Multiple Mirror ...

The quaternary mirror (M4) of the Extremely Large Telescope will be equipped with an Adaptive Optics Unit, in order to compensate the effects of the atmospheric turbulence. The highly accurate, closed loop actuation of the thin mirror is provided by 5316 contactless actuators. Their core ... Per saperne di più
Transducer optimization is a key aspect for successful development and deployment of advanced sensors, especially when designing 3D structures for harsh environments. For piezoelectric transducers, plate thickness determines the operating frequency of the resonator, which is frequently ... Per saperne di più
Three efficient alternatives to the model in COMSOL’s thermoacoustics interface are presented. The higher efficiency of these models are explained from theory and are demonstrated by means of two examples. Per saperne di più
