2.1. Measurement and Analysis of the Bicycle Weaving Motion
In order to understand the weaving motion, first it is necessary to obtain the dynamic information
about the 3D movement by quantifying the measurement of a bicycle motion in real environment. This
will provide the information necessary for correctly estimating the harvested output electrical power as
well as the mechanical boundary conditions needed for proper design of an energy harvester with high
electromechanical conversion efficiency. Unfortunately, there is not much data available in literature
about the weaving motion which might be contained in the lateral components of bicycle frame
motion. Therefore, we measured the acceleration of the bicycle weaving by using a MEMS-based
3-axis accelerometer and analyzed its amplitude and frequency characteristics.
