“…As occur to CNTs, the most used conductive matrices for PRSs developed with 2D nanomaterials including polymers and elastomers, namely, PVDF (Costa et al 2017 ), PDMS (Rajitha and Dash 2018 ), Ecoflex (Zhang et al 2019b ) (Joo et al 2015 ), Silly Putty (Boland et al 2016 ), poly (lactic acid) (PLA) (Scaffaro et al 2018 ), and other blends of elastomers. In most cases, PRSs based on graphene/polymer composite are more sensitive due to the large surface area of 2D graphene and its high carrier mobility (Chen et al 2017b ).…”

The wearable sensors have attracted a growing interest in different markets, including health, fitness, gaming, and entertainment, due to their outstanding characteristics of convenience, simplicity, accuracy, speed, and competitive price. The development of different types of wearable sensors was only possible due to advances in smart nanostructured materials with properties to detect changes in temperature, touch, pressure, movement, and humidity. Among the various sensing nanomaterials used in wearable sensors, the piezoresistive type has been extensively investigated and their potential have been demonstrated for different applications. In this review article, the current status and challenges of nanomaterials and fabrication processes for wearable piezoresistive sensors are presented in three parts. The first part focuses on the different types of sensing nanomaterials, namely, zero-dimensional (0D), one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D) piezoresistive nanomaterials. Then, in second part, their fabrication processes and integration are discussed. Finally, the last part presents examples of wearable piezoresistive sensors and their applications.

“…Flexible electrostrictive materials have numerous applications, e.g. in wearable sensors and MEMS [66][67][68] . Inspired by the introduction of dielectric mismatched nanodomains in a dielectric elastomer 69 and electronirradiated poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] copolymer 10 , a large electrostriction has been observed 17 in a composite of reduced graphene oxide (rGO) embedded in a polydimethylsiloxane (PDMS) matrix.…”

“…[1,3,23,31,53] This adds new functionalities to these materials and expands their use in several areas, such as electronics, detectors, sensors, and biosensors. [54][55][56][57][58][59][60][61] GO presents numerous oxygenated groups, such as hydroxyl and epoxide groups in the basal plane and carbonyl and carboxyl groups in the sheet edges, [62] and also retains a fraction of sp 2 -carbons as islands or hydrophobic domains. The combination of domains and functional groups render GO amphiphilic, and that has been widely explored for the selforganization of GO at interfaces, [23] such as the oil-water interface of emulsions.…”

Owing to their versatility and unique characteristics, graphene‐based materials have been used extensively for the development of electrochemical sensors and biosensors. The key to the maximum potential of these materials is the understanding of the role their structure plays in their modification processes. Herein, we summarize some structural characteristics of graphene oxide (GO) and reduced graphene oxide (rGO) and explore different surface modification methods for electrochemical sensing applications. surveyed the most recent applications of these materials as (bio)sensors, particularly for environmental monitoring and health‐related applications, such as quantification of biomarkers and metabolites and detection of cancer cells. The low detection limits, selectivity toward target molecules, and robustness of GO‐ and rGO‐based electrodes render them critical materials for the preparation of sensors for routine analysis and monitoring.
