Airspeed information plays a crucial role in the takeoff, flight, and landing processes in animal flyers and aerial vehicles. Among the aerial vehicles, Flapping Wing Micro Air Vehicles (FWMAVs) represent the novel engineering approach of learning and mimicking animal flyers in the past two decades. A few prototypes of various sizes and...

This thesis explores the challenges of using ultrathin graphene membranes in microelectronic mechanical sensors (MEMS) technology, specifically in the development of MEMS microphones. Graphene, being only an atom thin and one of the strongest known materials, offers promising potential for further miniaturization of MEMS microphones. However,...

Though NanoSats are becoming increasingly capable of featuring active payloads, and acquiring inertial data at arcsec level precision; the payload operational duty-cycle largely remains limited by its data downlink capabilities. NanoSat laser communication terminal (LCT) promises 1 Gbps data downlink capabilities. However, LEO to ground free...

Electron microscopy has enabled us to visualize objects that are not observable with a light microscope. With Transmission electron microscope observation up to subatomic level is possible. Generally, the sample is under vacuum in an electron microscope. But in real life sample is under influence of environmental conditions like liquid, gas,...

At this moment there are more than 150 different designs of CMMA in existence. To aid the designer to develop a new or improved CMMA or choose what the design to use, a classification system is developed during the literature research. It is based on the geometrical advantage (GA) of the CMMA, and on the input and output port motion paths. Their...

Ever since its inception, graphene has been the subject of research in many parts of the<br/>world. This is due to its exceptional mechanical and electrical properties, which makes it<br/>ideal for NanoElectroMechanical (NEMS) devices. The inherent nature of NEMS devices,<br/>includes low damping, large amplitudes of oscillation, resonant...

MEMS devices are currently designed to avoid sliding and contacting parts due to friction and adhesion problems. In this work, the possibility to grow a low friction material locally on MEMS sidewalls is investigated. An overview of the lubricants proposed in the literature for the microscale is presented, and graphene is selected as a promising...

In this work, we have incorporated heaters in a MEMS device, which allow the in situ local heating of its contacting surfaces. This design offers a promising solution for MEMS devices with contacting components by preventing capillary-induced adhesion. The force of adhesion was assessed by optically measuring in-plane snap-off displacements. We...
