A Study on Energy Harvesters for Physical Unclonable Functions and Random Number Generation
(Virginia Tech, 2017-08-04)
As the broad implementation and use of wireless sensor nodes in Internet of Things (IOT) devices increase over the years, securing personal data becomes a growing issue. Physical unclonable functions (PUFs) and random ...
A New Approach to Wide Bandwidth Energy Harvesting for Piezoelectric Cantilever Based Harvesters
(Virginia Tech, 2013-03-27)
This thesis proposes a control system to widen the bandwidth of piezoelectric transducers (PZTs) for vibration energy harvesting while extracting maximum power. A straightforward complex conjugate match achieves maximum ...
Power Converter Design for Maximum Power Transfer and Battery Management for Vibration-Based Energy Harvesting on Commercial Railcars
(Virginia Tech, 2015-06-24)
Although the locomotive of a train is energized, in general, other railcars are not. This prevents commercial rail companies from installing sensor equipment on the railcars. Thus, several different solutions have been ...
