摘要：

A new approach has been described to discuss how smart materials could be devised using the novel hetero-core sensors intended for monitoring large deformation in terms both of the curvature and the direction of bending in the form of pad-structures made of rubber. The result showed that the proposed pad-structures were sufficiently sensitive to the given curvature and directions for deformation with a sufficient linearity of sensor characteristics. The hetero-core embedded pad sensors were successfully perceptive for the first time with typical sensitivities of 0.066 and 0.153 dB/mm as a smart material to know not only the deformation direction but also the degree and convex/concave direction of curvatures.
