A Fully Integrated Materials Framework for Enabling the Wireless Detection of Micro-defects in Aging and Battle-worn Structures (Year 1)

Abstract

We present first-year results from a two-year study on a novel, inexpensive, passive, wireless solution for performing nondestructive evaluation on the structural integrity of aging aircraft. Compact, frequency-selective, backscatter transponders have been designed for operation in the industrial, scientific, and medical (ISM) frequency bands. These circuits rely on a novel metal-insulator-metal (MIM) complimentary split ring resonator (CSRR) design incorporating a multilayered substrate. We have performed initial evaluations on the electrical and electro-acoustic properties of barium strontium titanate (BST) and lead zirconate titanate (PZT), respectively. Additionally, results from the development of a process-compatible integrated resistor and a novel through-wafer interconnect technology are presented.
