Fluid-Structure Interaction Modeling for an Optimized Design of a Piezoelectric Energy Harvesting MEMS Generator
Publié en 2011
This paper reports the design of a piezoelectric energy harvesting micro generator for an energy autonomous tire pressure monitoring wireless sensor node. For our design we use a piezoelectric MEMS generator approach without additional mass. The intrinsic mass of the cantilever is in the microgram region and the resulting acceleration forces are very small.
The generator has a triangular shape to enable a uniform stress distribution in the horizontal surface direction. The cantilever consists of a carrier layer realized in silicon and a piezo layer. The carrier layer serves three purposes: it provides mechanical stability of the structure, it contains the neutral axis and it is used as a storage element for the harvested mechanical energy.
