Footprint Reduction for the Acoustic Electric Feedthrough Technique

Abstract

This report outlines progress towards reducing the footprint of the DSTO Acoustic Electric Feedthrough (AEF). The AEF approach is being explored as a potential means of wirelessly powering in situ structural health monitoring systems embedded within aircraft and other high value assets. In previous work it was shown that power and data communications can be transmitted ultrasonically through thin aluminium plate using an AEF formed with 38 mm diameter piezoelectric disks. In this report it is shown that a small-sized AEF system formed using 10 mm diameter piezoelectric disks (equating to a footprint reduction of 93%) has a power transfer efficiency of 42% and data transfer rate of 115 kBits per second, equivalent to the capabilities of the previously examined AEF arrangements with significantly larger footprint. Two-dimensional finite-element models are developed and shown to have sufficient fidelity to assist with future AEF design and optimisation.
