Abstract
The present teachings provide apparatus and methods for measuring the power output of a person, such as a cyclist. According to various embodiments, while measuring the power output, the present teachings provide for the harvesting of the input energy to provide electrical power to the apparatus. Among others, embodiments are described wherein power measurements are obtained from the drive train of a bicycle by making use of piezoelectric element(s) capable of producing electricity when deformed by applied forces. In addition, telemetry information of the applied forces can be obtained with the use of an inertial measurement unit.
