Abstract
Energy harvesting with cantilever beam is the most commonly used method for small electrical input devices like sensors etc. Uniform cantilever beam with no concentrated mass at the end produces less energy than the beam with concentrated mass at end. In this paper, instead of addition of the tip mass, single step beam with no concentrated mass is studied. Stepped beam with less stiff end as fixed end, given excitation at the base showing better results than the uniform beam with base excitation at the fixed end in form of transmissibility function. Frequency response function (FRF) has been plotted for voltage output, current and power, showing good results than the uniform beam. While comparing the results between the uniform beam and stepped beam the total mass kept equal.
