Carbon nanotube(CNT)-dispersed resin is expected to be a highly sensitive and remote strain sensor without interconnections. Application of microwave showed the possibility of the non-contact measurement of the change of electrical impedance of the resin under dynamic load by measuring the change of its reflectivity obtained from the surface of the resin. A theoretical method to estimate the change of the intensity of the microvave reflected from the resin was discussed based on the microwave theory. The change of the reflectance under tensile strain of 20% was calculated by the method using the measured change of the impedance of the resin under the frequency range between 1 Hz and 10MHz. As a result, the maximum change of the reflectance was estimated as 1.2% at 630 kHz.
