Vibrational Energy Harvesting Piezoelectric Harvesting Capturing the forces of small oscillations and turning them into electricity via the piezoelectric effect found in specific materials Piezoelectric Effect Some materials can generate an electric charge in response to applied mechanical stress Making small movements count Vibrations can be amplified at natural frequencies with an inertial mass to induce oscillations that extend the energy duration Every movement has energy Vibration harvesters use rapid small movements of piezo material to produce alternating electricity Efficient conversion to DC Advanced electromagnetic generators turn the force into electricity Uninterruptable, endless power supply Advanced power management circuits regulate storage and output providing endless power Battery free, harsh-environment storage Supercapacitors store charge to cover times of intermittency or high output What are the applications?
