Abstract: Provided is an energy harvester and an engine monitoring system. An engine monitoring system using an energy harvester includes at least one or more self-power generation wireless sensor nodes for generating electric energy using the energy harvester and monitoring an engine; and a management server that receives and manages sensing information received from the self-power generation wireless sensor nodes. The self-power generation wireless sensor nodes includes sensor modules monitoring the engine; a data processing unit identifying and packaging sensing information; a wireless communication unit wirelessly transmitting the packaged sensing information to the management server; the energy harvester generating electric energy to be supplied to the sensor modules, the data processing unit, and the wireless communication unit by converting vibration energy of the engine into the electric energy; and a power management unit controlling the electric energy to supply the electric energy to the sensor modules, the data processing unit.
