dc.description.abstract | This work presents an experimentally validated impedance-based finite element model (FEM) of a highly-coupled prestressed piezoelectric energy harvester (PEH) with piezoelectric multilayer stacks (PMSs). The FEM first simulates the
status of the PEH as a result of the static pre-stress. It then analyses the internal impedance || of the pre-stressed PEH,
which is used as the optimal load resistance for power output generation. The developed FEM is able to precisely
predict (1) the maximum power output at each frequency without the tedious load-resistance sweeping approach
traditionally used; (2) the dual-power-peaks phenomenon of highly-coupled PEHs, which cannot be observed when using
the traditional approach of = 1⁄. This model provides a useful tool for the design and optimization highlycoupled piezoelectric energy harvesters. | en_GB |
