2. Analytical and Numerical Study of a Passive Self-Tuning Resonator
University essay from Lunds universitet/MekanikAbstract : Energy harvesting, from ambient vibrations, can be a very effective method for solving the problem with powering electronics were the need for constant power or regular battery replacements is a trouble or an inconvenience. But, since all energy harvesters, using mechanical vibrations, need to operate in resonance in order to generate maximal electrical output, and ambient vibrations usually do not have a constant vibration frequency, this results in the need for efficient self-tuning systems.

3. Designing an Experiment to Investigate Slow Light Effects in Whispering Gallery Mode Resonators
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Slow light and Whispering Gallery Mode Resonators are two interesting and useful fields with applications in optical sensing and laser stabilisation among others. Slow light can lead to long interaction times which are useful in light-matter interactions such as sensitive non-linear optics. READ MORE

4. Novel micromechanical bulk acoustic wave resonator sensing concepts for advanced atomic force microscopy
University essay from KTH/Mikro- och nanosystemteknikAbstract : This thesis investigates novel concepts of micromechanical bulk acoustic wave sensors for advanced atomic force microscopy (AFM), using micromachined silicon resonators, which are analyzed with regard to their performance as compared to conventional AFM sensors. Conventional AFM systems use a cantilever resonator for sensing the surface forces of the sample. READ MORE

5. Single and double clamped resonator sensors - Design, fabrication and testing
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : Micro- and nanomechanical single and double clamped resonators are widely being used as mass and temperature sensors due to their high sensitivity, as bio sensors due to their real time label-free detection ability. These resonators have attracted considerable interest from applications like point of care diagnostics, homeland security and environmental monitoring in recent years. READ MORE
