The cover depicts polymer “microfins” embedded in pH‐responsive gel and submerged in water. Actuation of the fins driven by volume phase transitions in a pH‐responsive hydrogel “muscle” may be able to drive the flow of particles in solution, as proposed on p. 1442 by Joanna Aizenberg and co‐workers. The system is designed to provide uniform directional bending actuation over a large area and integrated with electrochemical and microfluidic cells.
