Harmonic poly-actuator : design and control of a new piezoelectric mechanism
… be amplified, typically through mechanical or frequency leveraging. Both have inherent limitations: mechanical devices can increase the stroke but is naturally limited; and frequency devices relies on friction and is limited to nanopositioning. In this thesis, we investigate combining a unique …

Microstrip Superconducting Quantum Interference Devices for Quantum Information Science
<p>Quantum-limited amplification in the microwave frequency range is of both practical and fundamental importance. The weak signals corresponding to single microwave photons require substantial amplification to resolve. When probing quantum excitations of the electromagnetic field, the substantial …

A study of a piezoelectric energy harvesting system using magnetorheological fluids
… fluid as a soft impact mechanism to enhance the frequency of the energy generator. Currently, the major bottleneck of vibration energy harvesting is the dynamic nature of vibrations in the environment which necessitates that vibration energy harvesters change their frequency to match that of the …
