2007 "Piezoelectric Generator Harvesting Bike Vibrations Energy to Supply Portable Devices" Applied Mathematics and Mechanics

With the decrease in energy consumption of portable electronic devices, the concept of harvesting renewable energy in human surrounding arouses a renewed interest. In this context, we have developed a piezoelectric generator that harvests mechanical vibrations energy available on a bicycle. Embarked piezoelectric transducer, which is an electromechanical converter, undergoes mechanical vibrations therefore produce electricity. A static converter transforms the electrical energy in a suitable form to the targeted portable application. Values of generated electrical power are reported and commented
