Abstract
Disclosed is a fine dust collecting device using a human body based electrostatic energy harvesting element. The fine dust collecting filter device includes an electrostatic energy harvesting element for collecting and generating current; a charging filter connected to the electrostatic energy harvesting element such that the charging filter is electrically charged to have a first polarity and thus electrically charges fine dust particles; a collecting filter connected to the electrostatic energy harvesting element such that the collecting filter is electrically charged to have a second polarity opposite to the first polarity; and a rectifier disposed between and connected to the electrostatic energy harvesting element, and the charging filter and the collecting filter.
