A New Approach to Wide Bandwidth Energy Harvesting for Piezoelectric Cantilever Based Harvesters
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 transfer only at a single frequency while requiring an impractically large...
