▎ 摘　　要

Nanomaterials have recently been extensively investigated for novel flexible device applications, especially in wearable and medical electronics. As an appealing form of graphene, crumpled graphene has some excellent features like ultra-thin, high stretchability, ease to fit human skin, tunable transparency and wettability. However, the fabrication process seriously limited its practical use. Here we propose a new method to transfer crumpled graphene to various substrates like PDMS, EcoFlex and GaAs, SiO2 wafers, which makes some new applications become possible. Moreover, the electric response of crumpled graphene under strain was extensively investigated. Crumpled graphene with good linear resistance-strain behavior and large stretchable range was obtained and used as strain sensors for human motion monitoring. High performance strain sensing was achieved featuring large stretchable range, high reliability, biocompatible construction and the ability to integrate with other devices. (C) 2017 Elsevier B.V.
