Abstract
A disclosed apparatus includes sensors incorporated into adhesive material. In use, an apparatus may comprise an adhesive material and at least one split-ring resonator (SRR) disposed on or in the adhesive material. Additionally, the at least one SRR is formed from a carbon-containing material, and the adhesive material is a non-elastomeric material or a semi-rigid material. In some aspects, each SRR may resonate at a first frequency in response to an electromagnetic ping when the adhesive material is in a first state, and may resonate at a second frequency in response to the electromagnetic ping when the adhesive material is in a second state. A resonant frequency of the adhesive material may be based on physical characteristics of the adhesive material.
