Abstract
This paper reports a two-dimensional isotropic and biodegradable sensor for soil pH monitoring. The sensor is operated wirelessly through split-ring resonators (SRRs) that consist of patterned hydroxyapatite (HA)-coated magnesium (Mg) on a poly-lactic acid (PLA) film. In acidic conditions, the degradation of each SRR results in a change in the electromagnetic response of the sensor. We demonstrate the operation of the sensor in two different acidic soils (pH>5 and
