The drop of power requirements of micro-electronic devices allows confidence that piezoelectric energy harvesting (PEH) is able to reliable power a wireless sensor network (WSN). The present work summarizes results of ongoing research in the field of PEH. With the aid of a performance metric a comparison between various devices is performed. A brief description of modeling a piezoelectric multilayer-beam as energy harvester is presented, followed by a concept of multi-objective optimization. This summary should give an idea of current state of the art and a rough guideline when designing a PEH.enpiezoelectric energy harvestingsmart structureswireless sensormulti-objective optimization620621004conference paper
