Based on a thermally reduced graphene oxide (rGO)/carbon nanotube (CNT) composite film, two kinds of flexible, wearable, and ultralow-power-consumption electronic skins (E-skins) are prepared. They have been used to successfully perceive the signals of stretch, flexion, temperature, and pressure, and their gauge factors (GFs) are 233, 2.37 rad–1, 5.53 × 10–4 °C–1, and 1.58 kPa–1, as the mass fraction of graphene is 20% in the composite film. Compared with the E-skins based on pure rGO film, our E-skins have larger stretching stain (ε) and bending angle (θ) ranges and higher temperature- and pressure-based GF values. Furthermore, the prepared E-skins have been successfully applied in various fields, and their ultralow power consumption has also been confirmed to be below 72 nW in wearable device applications.
