For wireless strain sensing, we utilize metamaterial array architectures for high sensitivity and low nonlinearity-errors in strain sensing. In this work, telemetric strain measurements in three test materials of cast polyamide, derlin and polyamide are performed by observing operating frequency shift under mechanical deformation and these data are compared with commercially-available wired strain gauges. We demonstrate that hard material (cast polyamide) showed low slope in frequency shift vs. applied load (corresponding to high Young's modulus), while soft material (polyamide) exhibited high slope (low Young's modulus).EnglishElastic moduliElasticityElectronic equipmentFrequency shift keyingMaterialsMetamaterialsPosition measurementStrain gagesApplied loadsArray architectureFrequency shiftHard materialHigh sensitivityHigh slopesIndustrial materialsLow young's modulusMechanical deformationNon-LinearityOperating frequencySoft materialStrain gaugeStrain sensingSurface strainsTest materialsYoung's ModulusStrainArticle10.1364/OE.18.005000
