A multi-responsive actuator based on paper and polymer composite is fabricated by a Pencil-on-Paper method, which is described by L. Chen, W. Zhang, C. Liu, and co-workers on page 7244. A colorful biomimetic flower and a smart curtain are also fabricated to demonstrate the applications. This work has great potential in the fields of lab-on-paper devices, artificial muscles, robotics, and biomimics.
