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.
