“…The FTIR spectra of the Ni-coated and PPy-coated fabrics are presented in Figure 3(a). The profile of the pristine cotton fabric exhibited the absorption peaks at 1425, 1359, 1159, 1028 and 898 cm −1 , which were due to the –CH 2 and –OCH in-plane bending, C–O–C stretching, C–O stretching and glucose ring stretching of cellulose, respectively [28,29]. For the Ni-coated fabric, these typical bands of cellulose could not be found, further demonstrating the dense coverage of the Ni layer on the fabric surface.…”

Continuous real-time human motion and heart-rate monitoring systems can provide vital clinical information for disease diagnosis, preventive healthcare and rehabilitation care. However, it is still a challenge to design wearable pressure/strain sensors with great flexibility and sustainable power for motion detection and physiological signal monitoring. Here, a self-powered laminated fabric sensor based on Schottky contact was successfully fabricated. This laminated fabric sensor was constructed by sandwiching the polypyrrole (PPy)-coated fabric with the Ni-coated fabric and Al plastic film. The electrical outputs under strain were attributed to the single Schottky contact between PPy and Al. This fabric sensor exhibited excellent stability under continuous quick cycling operation and at high relative humidity, which could be adapted to different human body parts for continuous motion detection and heart-rate monitoring. This work is of great significance to demonstrate a promising strategy toward self-powered wearable pressure sensors used for human motion detecting and hear-rate monitoring.

Among various energy storage and conversion materials, functionalized natural clays display significant potentials as electrodes, electrolytes, separators, and nanofillers in energy storage and conversion devices. Natural clays have porous structures, tunable specific surface areas, remarkable thermal and mechanical stabilities, abundant reserves, and cost‐effectiveness. In addition, natural clays deliver the advantages of high ionic conductivity and hydrophilicity, which are beneficial properties for solid‐state electrolytes. This review article provides an overview toward the recent advancements in natural clay‐based energy materials. First, it comprehensively summarizes the structure, classification, and chemical modification methods of natural clays to make them suitable in energy storage and conversion devices. Then, the particular attention is focused on the application of clays in the fields of lithium‐ion batteries, lithium–sulfur batteries, zinc‐ion batteries, chloride‐ion batteries, supercapacitors, solar cells, and fuel cells. Finally, the possible future research directions are provided for natural clays as energy materials. This review aims at facilitating the rapid developments of natural clay‐based energy materials through a fruitful discussion from inorganic and materials chemistry aspects, and also promotes the broad sphere of clay‐based materials for other utilization, such as effluent treatment, heavy metal removal, and environmental remediation.
