Design of A Microcontroller Based System for Harvesting Electricity from Exercise Bike

Regular exercising is one of the key factors to stay healthy. On the other hand, harvesting electricity from clean renewable sources is crucial for the environment. In this paper, we combine these two important aspects of our lives. An electricity generating device coupled with a stationary exercise bike is presented in this paper. A lead-acid battery was charged with the help of our developed prototype. Regular usage of this device can not only help a person stay healthy, but also can reduce the pressure on fossil fuel based generation of electricity. Our developed prototype will be able to recharge the batteries of UPS, which can be used in case of emergency power outage. Several tests were conducted using our developed prototype, where the battery accumulated 16.7% charge in a little over 2 hours.
