De La Salle University-Dasmariñas Senior High School students are currently conducting two researches on Piezoelectric (pressure electricity) technology that are already yielding positive results.
Piezoelectric technology or creating energy from mechanical pressure was chosen as a topic by the group of Julianne Marie N. Alicdan, Charlyn Angela B. Cheng, Angela Nicole P. Hernandez, Lyconia Manea A. Leynes, Denisse Gwen R. Oli, Danielle Mari C. Tanael, Eliyah Jane A. Tuazon, and Rafael Angeleo Miguel M. Villamor who wanted to promote this alternative source of energy.
The study entitled: “Piezoelectric Pedestrian Crossing as a Sustainable Energy Source and Its Impact on the Behavior of Pedestrians” seeks to determine the change in behavior of pedestrians when crossing the street and to create a crosswalk that can produce sustainable electrical energy when force is applied unto the device.
"Not all people are aware of what piezoelectricity is. We want people to know that this device could be the next alternative source for electrical energy. With just a step, you could create electrical energy," Leynes said about the study. The study has already recorded a generation of energy.
Meanwhile, the group of, Kenneth D. Borlado, Joshua Luigi C. Delos Santos, Hans Francis M. Lugo, Matthew Ivan E. Rosaro, and Gabriele Andrei Z. Samson are currently embarked on a study entitled “The Development of an Arduino Based Piezoelectric Energy Harvesting Shoe.”
The study seeks to develop a piezoelectric shoe which is designed as a portable charger and whose energy will be equal to the number of steps the user takes. It is a device that utilizes the energy exerted from human locomotion and converts it into electrical energy.
“We have seen multiple designs utilizing piezoelectric materials as an energy mat. A big sheet of cloth or metal with piezoelectric material underneath that converts the kinetic energy from the people walking over it into electrical energy for future use. That concept for me is too confined. The energy exerted by people not walking over those mats just gets wasted so, why not get the energy directly from people's feet?" Borlado said.
