Abstract:
The present invention provides an piezoelectric based energy harvester apparatus [20] consisting of a specially designed mechanical structure, hollow cylindrical structure [30] with a piezoelectric cantilever bridge [34] within its chamber, that upon exposure to the collected rain water incoming from the roof structure [24] into the post [26], will move or vibrate due to buoyant force of the strategically trapped rain water. With the structure built-in mechanical cantilevers bridge [34] that has piezoelectric properties, the vibration of the cylindrical structure [30] is followed by the generation of micro energy. Therefore, besides serving its traditional purpose for protection, post/pillar can also be used to produce energy which can power up low power electronic devices such as for precision agriculture application. This apparatus can also act as an alternative energy harvester during raining season where no sunlight is available. Fig. 2
Abstract:
The present invention discloses an apparatus and method thereof which is suitable for harsh environment, wherein it is able to provide a wide variety of measurements or detections and effective monitoring of sample of harsh environment. The collected data subsequently is converted to digital data and thus wirelessly transmitted to a suitable gateway, said gateway is preferably World Wide Web based.
