Abstract

In this work, we present a novel, geopolymer temperature-sensing patch which can be heated using induction and used to infer thermal conductivity of the surrounding medium. The sensor patches, applied to concrete specimens, were fabricated by loading a geopolymer binder with 0 - 60 wt% ground magnetite. The magnetite content allowed the patches to be heated using an induction coil, while temperature profiles were monitored via changes in patch electrical impedance. Sensor patches were left uncoated, or were coated in surface-water, soil and sand. Each material provided a unique thermal signature which, with simple signal processing, could be used to reliably detect whether the patch was buried.
