“…Patterned graphene has been proved to be an excellent deformation sensitive material for flexible strain sensors in previous studies. [ 37–41 ] However, few studies focus on the substrate/graphene interface modification to optimize the basic performance of sensors. Our graphene patterning technique also represents an effective interface enhancement method and meets the sensor requirement of high sensitivity.…”

In recent years, graphene based flexible strain sensors have attracted great attention. Although various designed micro/nanostructure morphologies have been introduced to optimize the performance parameters such as sensitivity and working range, there are relatively limited studies on the effective patterning of graphene on various substrates on curved surfaces to manufacture functional devices. In this work, we report a general route to realize the patterning of graphene into predesigned structure on a variety of complex curved substrates. The methodology involves a combination of polydopamine surface modification of the substrate and the spraying process of graphene. The polydopamine modification method preserves the intrinsic electrical properties and stability of graphene, and the modification process by self‐polymerization of dopamine is available on many types of materials of complex shape. This general approach of interface modification to achieve free patterning has capability of large‐scale fabrication. By this interface‐enhancement patterning method, sensing structure of cut‐through channel crack has been obtained, resulting in flexible strain sensors with adjusted high sensitivity (gauge factor of 100–2000 at 1% strain), little hysteresis and conformality of complex surfaces. In addition, the strain sensor array has also been fabricated to detect the deformation spatial distribution of complex curved structural components, thereby expanding their potential applications in wearable electronics.

“…The adoption of elastomer (as matrix to form composite or function as substrate) and structural design can improve stretchability of on‐skin electrodes, while metallic nanomaterials based composites usually demonstrate high conductivity due to superior high conductivity of metals. For instance, stretchable polymer substrate such as silicone‐based substrates, [ 56,200 ] textile‐based substrates, [ 201 ] and protein‐based substrates [ 202 ] had been investigated and elastic composites such as PDMS−ECCs, [ 102 ] AgNWs–PDMS mixtures, [ 103 ] and Ag‐PU nanocomposites [ 101 ] had been synthesized. Regarding structural design, typical deformable structures such as filamentary serpentine, [ 203 ] wrinkles, [ 60 ] and kirigami [ 204 ] have been implemented.…”

On‐skin electrodes function as an ideal platform for collecting high‐quality electrophysiological (EP) signals due to their unique characteristics, such as stretchability, conformal interfaces with skin, biocompatibility, and wearable comfort. The past decade has witnessed great advancements in performance optimization and function extension of on‐skin electrodes. With continuous development and great promise for practical applications, on‐skin electrodes are playing an increasingly important role in EP monitoring and human–machine interfaces (HMI). In this review, the latest progress in the development of on‐skin electrodes and their integrated system is summarized. Desirable features of on‐skin electrodes are briefly discussed from the perspective of performances. Then, recent advances in the development of electrode materials, followed by the analysis of strategies and methods to enhance adhesion and breathability of on‐skin electrodes are examined. In addition, representative integrated electrode systems and practical applications of on‐skin electrodes in healthcare monitoring and HMI are introduced in detail. It is concluded with the discussion of key challenges and opportunities for on‐skin electrodes and their integrated systems.
