Abstract:
PURPOSE: A prognosis system using MEMS sensors driven by an energy harvester is provided to use vibration energy generated in machine equipment as the driving energy of a sensor or a sensor module. CONSTITUTION: A prognosis system using MEMS sensors driven by an energy harvester comprises a MEMS sensor, a wireless sensor unit(409), an energy harvest and a base station(411). The MEMS sensor unites with objects. The wireless sensor unit receives the sensor signal of the analog type from one or more MEMS sensors and signal-processes the sensor signal and converts the sensor signal into the digital signals. The sensor signal converted into the digital signal is produced as packet data. The produced packet data are wirelessly transmitted to the base station. The energy harvest converts the vibration energy of the objects and supplies driving energy to operate one or more among the MEMS sensors and the wireless sensor unit. The base station receives and synthesizes the packet data. The base station analyzes the synthesized packet data and drives prognosis diagnosis based on the analyzed data and produces the prognosis diagnosis result.
