Surfing on chemical waves: a simple yet dynamically rich two-sphere responsive gel swimmer
Joseph J. Webber, Thomas D. Montenegro-Johnson
Self-oscillating gels are chemically-responsive hydrogels coupled to an oscillating chemical reaction of a stimulus solute. In response to the oscillating solute concentration fiel…

Oscillating chemical reactions enable communication between responsive hydrogels
Joseph J. Webber, Thomas D. Montenegro-Johnson
Responsive hydrogels can sense environmental stimuli and respond as actuators by expelling water and changing shape. In this article, we develop theory to demonstrate that groups o…

Poromechanical modelling of responsive hydrogel pumps
Joseph J. Webber, Thomas D. Montenegro-Johnson
Thermo-responsive hydrogels are smart materials that rapidly switch between hydrophilic (swollen) and hydrophobic (shrunken) states when heated past a threshold temperature, result…
