Abstract:
This study investigates the design, development, and performance evaluation of a piezoelectric combat pad that converts kinetic energy from punches into measurable electrical energy. The research will also establish the electrical output produced in the prototype at different punching rates and to test the correlation between the punch frequency and energy production. The system makes use of ten piezoelectric discs which are placed in parallel and connected to a full-wave bridge rectifier which transforms mechanical impacts into electrical signals. Experimental testing is carried out at the rate of punching 20, 40, and 60 punches per minute, and three experiments are carried out in each condition to guarantee data consistency. A digital multimeter is used to measure electrical output in terms of current and voltage. Findings indicate that the prototype has an ability to achieve consistent electrical output in each of the test situations, with an average voltage of about 7 V at 20 and 40 punches per minute and 8 V at 60 punches per minute. The peak mean current output is at a rate of 20 punches per minute (0.21 A). Energy calculations show the highest mean energy to be produced at 20 punches per minute (86.0 J). Pearson correlation analysis An analysis of the relationship between punching rate and generated energy can be seen as having a weak negative correlation (r = -0.272, p = 0.478), which suggests that the frequency of punching is not a key determinant of energy production. The findings demonstrate the potential of integrating piezoelectric technology into sports equipment as a small-scale energy harvesting system, contributing to sustainable energy innovation.
