Abstract
A droplet-based energy harvester is proposed. The droplet-based energy harvester may include a plate comprising a first surface and a second surface opposite to the first surface while being inclined such that a droplet flows on the first surface. The harvester may also include an upper electrode formed on the first surface, and a lower electrode formed on the second surface. The upper electrode may include a first upper electrode and a second upper electrode. The first upper electrode may be configured to emit electrons when the first upper electrode is connected to the second upper electrode by the droplet. The second upper electrode may be configured to absorb the electrons when the second upper electrode is connected to the first upper electrode by the droplet.
