Abstract :
This thesis experimentally studies the possibility of thermal energy harvesting using coupled shape memory alloy (SMA)and pyro-/piezoelectric material. This method is promising for harvesting slow & small temperature variations. First prototypes of energy harvesters were fabricated and their ability to produce an increased amount of specific energy was shown. Technologies of Ti-Ni-Cu SMA thin layer deposition & patterning were developed. This work will serve as a base for future fabrication of chip-scale thermal energy harvesters exploiting SMAs.
