Energy harvester design inspired from fractal geometries

Fractal-based geometry concept is exploited in a wide range of applications such as planar antenna for RFID tags or for RF energy harvesting by maximizing the length of the radiating material being compact in size and giving multi-band or broadband operation capabilities, and also as photodiode harvester by increasing the perimeter-to-area ratio which translates into more collected charges.
Energy harvester inspired by fractal design has not been widely investigated yet.
The discussion is done on different types of vibration energy harvester having a numbers of transducers elements positioned in different parts of the cantilever elements in order to exploit different frequencies modes and also to increase the number of piezoelements that could add their voltages allowing to acquire more energy. Different configurations with their performances deduced from simulations will be described.
Work is in progress for exploring the advantages of fractal-inspired geometrical configuration.
