Underwater Highly Pressure-Sensitive Fabric Based on Electric-Induced Alignment of Graphene.

ABSTRACT: Wearable pressure sensors have received widespread attention owing to their potential applications in areas such as medical diagnosis and human-computer interaction. However, current sensors cannot adapt to extreme environments (e.g., wet and underwater) or show moderate sensitivity. Herein, a highly sensitive and superhydrophobic fabric sensor is reported based on graphene/PDMS coating. This wearable sensor exhibits great superhydrophobicity (water contact angle of 153.9°) due to the hydrophobic alkyl long chains and rough structure introduced by the Ar plasma. Owing to the network structure created by the electric-induced alignment of graphene sheets, an enhanced sensitivity (ΔI/I₀ of 55) and fast response time (~100 ms) are observed. Due to its superhydrophobicity and sensiti
