Structures including a measurement coating and methods of forming the same

Abstract

A structure includes a substrate and a coating applied over the substrate, the coating containing particles sized between 30 and 250 micrometers. A proportion of the particles to the carrier is between 40 and 70 by volume percentage. In response to excitation of the structure by a controllable excitation source, a first instrument monitors behavior of the particles to determine a first condition of the structure thereby. In response to an absence of excitation of the structure by the controllable excitation source, a second instrument monitors behavior of the particles to determine a second condition of the structure thereby.
