Photostimulated actuators can be remotely actuated and operated at high speed, making them potential candidates for soft robotics. In this study, a paper-based actuator activated solely by light was developed for weight lifting. A polymer blend, primarily made of agarose-poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS), as a photosensitizer, MXenes and methylene blue (MB) was employed on a paper substrate to produce a bilayer structure using a paintbrush technique. The resultant paper/polymer bilayer actuator was activated by light and showed effective bending and weight-lifting capabilities, which can contribute to wireless paper soft robotics and biohybrid robots.

Many plant materials in nature have the ability to change their shape to respond to external stimuli, such as humidity or moisture, to ensure their survival or safe seed release. A well-known example for this phenomenon is the pinecone, which is able to open its scales at low humidity due to the specific bilayer structures of the scale. Inspired by this, we developed a novel humidity-driven actuator based on paper.

In this paper, we present high-performance and versatile inkjet-printed paper photo-actuators based on two-dimensional (2D) nanomaterials. As a rapid fabrication method, inkjet printing of 2D materials is used to promptly fabricate photo-actuators in a bi-layer paper/polymer structure. Water-based and biocompatible inks based on graphene and molybdenum disulfide are developed based on liquid phase exfoliation and differential centrifugation technique.
