description	The technologies for energy harvesting technologies using human body action have attracted much attention as alternative resource to replace the common energy resources that have been exhausted in these few decades. Piezoelectric material that has been widely used in sensor technologies is able to produce electrical energy from mechanical energy. Therefore, this transducer can be used to harvest the wasted mechanical energy from human body action. Many researchers use this piezoelectric transducer to harvest the mechanical energy from human footsteps by inserting this transducer in shoes. However, the designated shoes sometimes are not convenient to wearers. In this research, the mechanical energy from the human footstep was harvested using floor tile inserted with piezoelectric transducers. Typically, the output of the piezoelectric transducer is low. Hence a bending mechanism which is divided into two parts, namely support housing and presser was designed to enhance the output piezoelectric transducer in this research.
