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
