- •
We proposed a piezoelectric harvester using the principles of magnetic pendulum movement and impedance matching for self-powered safety sensor of trains.
- •
We used moment of inertia theory for proving the optimal condition.
- •
This harvester generated 40.24 μW/cm3 in the optimal condition.
- •
We proposed a system of self-powered recording system of the vibration and acceleration data of the train including circuit design.
