Abstract
Recent efforts centered at Sandia National Laboratories have demonstrated transmission of power and data through continuous metal media using vibration in connection with piezoelectric tiles; however, solid metal construction may be disadvantageous in structural contexts due to the greater mass needed to achieve given stiffness characteristics. Other common structural materials, on the other hand, such as aluminum honeycomb panels, may offer poor transmission possibilities when their characteristics are not appropriated accounted for in the selection of transducers. In this study, COMSOL simulations of the aluminum honeycomb panel materials were used to select transducers with resonance frequencies in proximity to the natural modes of the panel's honeycomb cells. This enabled improved transmission through the honeycomb panels in comparison to less targeted approaches. [SNL is managed and operated by NTESS under DOE NNSA Contract No. DE-NA0003525.]
