The features of the new designed and constructed harvester are examined. The harvested power of three piezoelectric layers having different masses (i.e. different natural frequencies) has been explored. These layers have the same length around the harvester body, whereas a permanent magnet (PM) attached to the shaft rotates by low speed wind and this PM repels these three piezoelectric layers with...
This paper reports the preliminary results of a new designed harvester system called as the contactless piezoelectric wind energy harvester (CPWEH). It consists of three piezoelectric layers attached with the non-magnetic bars in different lengths in order to produce maximal power for a wide wind wide speed regime. Preliminary magnetic design has proven that three layers can be excited by the magnetic...
