Abstract The photoactuation of pen arrays made polydimethylsiloxane carbon nanotube composites is explored, and the first demonstration photoactuated pens for molecular printing reported. Photoactuation these characterized using atomic force microscopy found to produce microscale motion in response modest illumination, with an actuation efficiency as high 200 nm mW −1 on sub‐1 s time scale. Arrays composite are synthesized it that local illumination capable moving selected by more than 3 µm out plane, bringing them into contact perform controllable quality while completely shutting off nonilluminated counterparts. In light scalability limitations nanolithography, this work presents important step paves way arbitrary control individual massive arrays. As example a scalable soft actuator, approach can also aid progress other fields such robotics microfluidics.
