Experimental Data for a Piezoelectric Shoe-Based Energy Harvester

This dataset accompanies the research article, “Design, Fabrication and Preliminary Experimental Evaluation of a Piezoelectric Shoe-Based Energy Harvester for Low-Power Applications.” It contains documented prototype specifications and performance values from the authors’ original university project on a wearable piezoelectric energy-harvesting shoe. The dataset includes the documented number of piezoelectric discs, voltage and current measurements, reported power output, test subject mass, battery specifications, rectification components, and related prototype information. Fourteen piezoelectric discs were used per shoe, giving 28 discs across the pair. The documented performance record reports approximately 0.5 V and 0.2 mA for each shoe, 1.0 V and 0.4 mA as aggregate values, and a reported power figure of 200 µW under the documented test configuration. The dataset also separately identifies calculations and claims reported in the original project documentation, including the reported 9-hour charging time and 64,750-step estimate. These values are included for transparency but are not presented as independently validated measurements because the original record does not provide sufficient information about electrical load, measurement duration, repeated trials, battery state of charge, or direct energy-per-step measurement. No participant names, contact information, photographs, or other direct identifying information are included. The dataset is intended to support transparency and reproducibility of the reported prototype documentation and to accompany the submitted manuscript.
