TL;DR: Novel trends for supplying WSN from ambient energy and by wireless energy transmission and possibilities for improving energy income by combination of converters within hybrid solutions are focused on.
Proceedings ArticleDOI
Design of a vibration energy harvester by twin lateral magnetoelectric transducers
TL;DR: A magnetoelectric vibration energy harvester based on a twin laminate composite of magnetostrictive and piezoelectrics materials was designed, developed and tested and results show that doubling the amplitude of vibration leads to an energy output which is four times more.
