Abstract
A vibration energy harvester that converts kinetic energy to electrical energy. The vibration energy harvester includes an electrically conductive coil array, a magnetic array and a self-assembled liquid bearing. The magnetic array is levitated above the electrically conductive coil array. The magnetic array and the electrically conductive coil array are configured to generate the electrical energy from a relative movement between the magnetic array and the electrically conductive coil array. The self-assembled liquid bearing separates the magnetic array from the electrically conductive coil array and levitates the magnetic array over the electrically conductive coil array.
