However, the rigidness of metal makes it dif?cult to develop a stretchable coil with low cost, and the system cannot work if the object is non-metallic. To overcome the limitations, an eddy current non-contact gap sensor system, in which both the coil and the object are made of stretchable conductive polymer composite, is designed. The current in the composite coil causes an induced current in the composite object covered on the non-metallic surface, leading to the occurrence of the eddy current effect. The experimental data show that the impedance of the composite coil changes regularly with the lift-off. The results verify the feasibility of using the system completely made of the composite to measure the non-contact gap between the non-metallic surfaces. ? 2016 Elsevier B.V. All rights reserved. 1. Introduction Eddy current effect plays an important role in the modern science and technology [1–3]. The non-contact gap measurements can be realized by using the eddy current sensor system [4–6]. In the traditional eddy current non-contact gap sensor system, both the coil and the object are made of metal. As the metal coil does not possess stretchability, it cannot be applied to the structures with high curvature. Furthermore, the eddy current sensor system cannot work if the object is non-metallic
