Energy Harvesting on Playground Slide with Implementation of Lead Zirconate Titrate (PZT) Cantilever and Gear System with IoT Monitoring

This paper assesses the design and implementation of a cantilever and gear system for a piezoelectric transducer for a playground slide. The prototype is composed of a roller playground slide that resembles an incline conveyor, gears, cantilevers, a battery, an Arduino Uno for monitoring, and sandbags to simulate the slide of child. The performance of the prototype is tested in every trial where parameters such as voltage, current, power, and efficiency were gathered and observed on controlled and uncontrolled conditions. With the IoT used as monitoring, the output power reached up to 4. 4mW which will charge 0.94% of the battery. This research is sustainable, safe, and help encourage kids in playing outside at playgrounds. This research also helps promote clean source of energy where the design can also be applied in other system that use rollers and/or conveyor.
