Abstract
AbstractFabric‐based sensors play a vital role in the development of wearable and flexible electronics. However, the research of wearable fabric‐based sensors with high sensitivity, wearing comfortability, ease of fabrication, superior stability, and fast response time is full of challenges. In this study, an all‐fabric flexible and wearable pressure sensor based on phosphorene‐gold nanocomposites (BP‐AuNCs) is developed. The sensor consists of a pair of screen‐printed interdigital carbon electrodes (SPICEs) and a BP‐AuNCs decorated fabric electrode. Benefiting from the microstructure of fabric fibers and the unique property of BP‐AuNCs, the developed pressure sensor presents excellent piezoresistivity, including a high sensitivity up to 0.372 kPa−1 (0–1.5 kPa), a rapid response time of 24 ms, good stability and durability (>4000 cycles), as well as washing durability. The distinguished performance of the flexible pressure sensor enables detection of subtle signal of human body motion, real‐time monitoring of wrist pulse and respiratory. Importantly, the proposed all‐fabric pressure sensor is fabricated by a simple process and is able to achieve high sensitivity while performing well in response time, wearing comfortability, stability, and reliability, demonstrating its great potential for smart wearable electronics.
