With haptic and pressure sensor manufacturing in the US totaling $US 1.6 billion in annual revenue—with 2% annual projected growth from 2018 to 2023—and tactical and service clothing manufacturing in the US totaling $US 242.9 million in annual revenue, the potential of advanced wearables continues to grow. As many fields tend toward miniaturized technologies in the modern age, many recent developments have been made for wearable platforms. Within the broad area of wearable platforms, there are many specific applications to consider, such as motion sensing, biomarker detection, monitoring of environmental pollutants, haptic sensors, enhanced soft robotics, and improving the safeguarding capabilities of armor. For these applications, the interfacial phenomena occurring between the continuous and discrete phases within the composite material are responsible for the device's response and bulk properties. Understanding these phenomena at the composite interfaces of the system allows for finer tuning of morphological, electromechanical, and other bulk properties, as well as the optimization of the wearable's output—in terms of the applications targeted. Control over these advanced composite materials is paramount in personalized health‐care systems, advanced defense technologies, commercial wearables. Recent advances on composite interfaces for wearable platforms are discussed, along with trends and an outlook of the field.

The on-body immunodetection of biomarkers in sweat would significantly augment the potential of wearable body-interfaced biosensors for self-testing but has been limited due to the difficulty of integrating liquid handling and immunobiosensing devices in a wearable platform. Herein, a stretchable microfluidic immunobiosensor (SMIB) patch with hollow microfibers of elastomeric nanocomposites for the highly sensitive on-body biosensing of neuropeptide Y (NPY), a stress biomarker, in human sweat is reported. The SMIB patch is composed of a stretchable liquid handling device and an electrochemical impedimetric immunobiosensor made of hollow and conductive microfibers of reduced graphene oxide (rGO) and rGO-Ag nanowires in polyurethane matrix, respectively. The patch possesses a low limit of detection of 50 fm, a large dynamic range (50 fm-1 nm), good linearity, no labeling or reagent requirements, and facile formation in a patch form factor. By combining handling of the biofluid and delivery of the washing solution by a simple finger-touch operation as well as the analytical capability of NPY with an extremely low concentration in human sweat, the SMIB patch is a promising approach toward wearable non-invasive immunodetection for self-testing.

Human sweat contains vast physiological information, which has been a promising resource for on‐body and real‐time health monitoring. Wearable sweat sensors have recently attracted an ever‐increasing interest due to their promising capabilities for continuously tracking changes in health status. However, the commercialization of sweat sensors is seriously hindered by drawbacks of materials including high manufacturing and consumables costs, complex integration technology, as well as limited electrochemical signal transduction. In this review, sweat sensing principles are elaborately interpreted, and the latest advances in functional materials for biomarkers sensing in sweat are systematically summarized. Subsequently, the complex structure–activity relationships between various functional materials and sensing capabilities are further elucidated by coupling chemical structures, geometrics, electrochemical properties, and approaches for materials manufacturing. Furthermore, the integration of each component into sensing device for sweat detection and analysis is also discussed. Finally, challenges and opportunities for wearable sweat sensors are delineated in the development of future personalized and predictive healthcare.
