The footstep power generation system using different configurations of piezo-sensors are analyzed in this paper. Energy generated by human walking, jumping and running is used as a source of energy which is converted to an equivalent electrical energy using piezoelectric effect. Experimental analysis of circular type piezoelectric sensors connected in different configurations- series, parallel and combination of series-parallel and sensors of various diameters show that series-parallel combination generates more voltage and is stable compared to other configurations. Circular type piezo sensor model is developed in the COMSOL Multiphysics simulator which shows near performance with the experimental results.
