Low-Power-Consumption Electronic Skins Based on Carbon Nanotube/Graphene Hybrid Films for Human–Machine Interactions and Wearable Devices
Source abstract
Abstract
Due to their excellent electrical and mechanical properties, carbon nanotubes (CNTs) and graphene (G) have attracted increasing attention for the application of electronic skins (E-skins). In this paper, based on CNT/G hybrid films with a resistivity of 4.98 × 10 –4 Ω·m, we prepared two kinds of E-skins with low power consumption and successfully realized the perception of multiple signals, including stretching, bending, temperature, and pressure. With a G mass fraction of 20%, the stretch/flexion/temperature-sensitive E-skin has an ultrahigh gauge factor (GF) of 1429 with a strain range of 0 to 10%, a GF of 0.92 rad –1 with a bending angle range of 0 to 90°, and a GF of 1.1 × 10 –3 °C –1 with a temperature range of 25 to 85 °C; the pressure-sensitive E-skin has a GF of 7.45 kPa –1 with a pressure range of 15 to 10,015 Pa. In addition, we applied the prepared E-skins in human–machine interactions and wearable devices and confirmed their low power consumption below 74.20 nW in wearable applications.
