Abstract

Test structures for energy harvesting through piezoelectric materials are designed using FEM. The results of the modelling are compared to those for fabricated devices which were tested using a perfusion machine to simulate blood flow. The results show considerable accuracy between measured characteristics and simulated ones which only differed by approximately 4%. The modelling also established the best design for energy harvesting using aluminium nitride (AlN) in blood flow.
