Furthermore, the CRSYs-based soft pneumatic actuators (SPAs) exhibit lightweight, high-load capability, easy programmable in strength and motions, and fast response, which outperforms currently reported elastomer-based SPAs, showing promising applications in flexible sensors, artificial muscles, and soft robotics. Moreover, the centrifugal reeling technique realizes the one-step preparation of centrifugally reeled silk yarn (CRSY) from spinning silkworm, and the CRSYs show higher strength (877.38 ± 377.23 MPa) and superior torsional recovery performances. Remarkably, the maximum strength (1.45 GPa) of CRS is 3 times that of cocoon silk and even comparable to spider silk. With this strategy, the centrifugally reeled silks (CRSs) with long-uniform morphologies, excellent strength (844.83 ± 319.48 MPa), high toughness (121.07 ± 35.31 MJ m-3), and outstanding Young’s modulus (27.72 ± 12.61 GPa) are developed. ![]() Herein, we report a facile and comprehensive strategy to fabricate high-performance silk materials from spinning silkworms artificially via a multi-task and high-efficiency centrifugal reeling technique. ![]() However, their inherent irregular morphologies, structures, and properties greatly hinder the translation of these technologies to commercial applications. ![]() Silkworm silks show increasing potential in the applications of bioengineering, sensors, optics, electronics, and actuators.
