Polymer gels undergoing the Belousov-Zhabotinsky (BZ) reaction exhibit colorful self-oscillations when chemical reagent concentrations are sufficient. It is demonstrated that when the reagents are depleted and the system reaches a steady-state, the oscillations can be resuscitated by applying macroscopic compression, thereby extending the useful lifetime of these materials. Pressure sensor applications are shown in which chemical signals are transmitted away from the deformation site.
