Carbon-based flexible wearable sensors have received widespread attention due to their wide application in wearable electronics. This work reviewed the different carbon-based sensors from three aspects, such as fabrication, performance and working mechanisms. Carbon materials mainly included carbon nanotubes, graphene, carbon black and other carbon materials. In particular, carbon nanotubes and graphene can be assembled into various multiscale macrostructures to prepare various forms of flexible sensors, such as films, fibers, yarns or fabrics. Up to now, the reviewed flexible strain sensors in general exhibit high sensitivity, wide sensing range, fast response, long-term stability and durability. However, in the face of complex environmental and multifunctional integration in practical applications, wearable strain sensors need new technological breakthroughs in the preparation process, material synthesis and device integration.

Joule heater based on single-layer graphene

et al. 2020

In this work, we have studied the characteristics of a heater based on single-layer graphene obtained by CVD using methane as the carbon precursor and using copper as a catalytic substrate. Synthesized graphene was transferred onto an EVA/PET substrate using a heat press printing method. A theoretical model of heating a polycrystalline graphene film was developed. The temperature gradients in graphene crystallites were estimated based on the model. It was shown that local overheating of graphene crystallite boundaries is the main cause of damage for the graphene-based heater. In order to enhance the power of graphene heaters, it is necessary to reduce the size of 2D graphene crystallites that make up the coating.

Nano-carbons including carbon nanotubes (CNTs) and graphite nanoplatelets (GNPs) have been proved to have good strain sensing capability, but they are often made together with flexible substrates, which may limit their multifunctional applications such as internal sensors. In this study, free-standing CNT/GNP buckypapers (BPs) with various weight ratios were prepared by filtrating their suspensions. Relative resistance variation depending on tensile strain of the obtained BPs was examined to evaluate their strain sensing capability, e.g. gauge factor (GF) and linearity (r 2 ) within the whole testing strain range. Results show that enhanced strain sensing capability of the hybrid BPs is obtained, with a maximum GF of 8.18, and r 2 of 0.999, respectively, in a relatively large strain range from 0% to 2%, when the GNP loading reaches 50 wt%. Moreover, in situ strain sensing capability of the hybrid BPs was practically monitored by sticking them onto the surfaces of epoxy resin. As expected, the hybrid BPs exhibit a relatively high in situ GF of 10.83 and r 2 of 0.987, as well as excellent repeatability and stability. Excellent strain sensing capability of the free-standing BPs reveal that they have potential applications in the fields of internal and external strain or damage monitoring.
