Frequency Modulation Approach for High Power Density 100 Hz Piezoelectric Vibration Energy Harvester
Piezoelectric vibration energy harvester (PVEH) is a promising device for sustainable power supply of wireless sensor nodes (WSNs). PVEH is resonant and generates power under constant frequency vibration excitation of mechanical equipment. However, it cannot output high power through off-resonance i...
