Working on alternatives for harnessing and transforming different forms of energy in a clean and efficient way, like piezoelectric phenomena, allows considering collecting energy that is commonly wasted.For example, the piezoelectricity facilitates the harvesting of energy derived from the weight discharged by humans when walking on a surface conditioned with piezoelectric transducers.However, the technology in this field has always advanced in the opposite direction, i.e. the conversion of electric energy into vibrations for different applications.In this work, the design of the material structure for a piezoelectric device of low resonance frequency for the capture of electricity is considered.The purpose of this device is the efficient transformation of mechanical energy into electrical energy; for this reason, the design of its configuration counts with a resonance frequency of less than 100 kHz.For this, the characteristics of the area dimensions and their relationship to the thickness according to the deposited material and the performance according to the projected impact were established.Moreover, the selection of the substrate was established according to the fracture requirements, acknowledging the mechanical loading loads of the transducer.
