<br/><br/> This research presents an alternative power source for bicycle users for developing an<br/>alternative electric generator using piezoelectric sensors installed in bicycle. The goal is<br/>to create an efficient way for bicycle users to charge their smartphones and signal lights<br/>while on the road. By attaching piezoelectric sensors in the saddle of the bicycle, the user's<br/>weight as well as the motion of the bicycle while cycling will function as mechanical<br/>energy that will be converted into electrical energy due to the piezoelectric effect which<br/>then will be stored in the lithium-ion battery and can be used as an alternative power<br/>source. This research also provides a mobile application for the users where it will display<br/>the real-time battery percentage and voltage of the lithium-ion battery. This monitoring<br/>system was created using MIT App Inventor and Thingspeak as a database. This research<br/>was evaluated using ISO 25010 as standard criteria for the efficiency of this project. The<br/>result of the evaluation answered by twenty respondents was obtained: the overall mean<br/>is 4.50, which has a descriptive rating of "Very Good." This signifies that the project has<br/>passed and is useful based on the respondents.
