Chemical oscillations are exploited to achieve self-expiring graphical information on paper-
based supports with precise temporal and spatial control. Writing and self-erasing processes
are chemically activated by exciting nonoscillating Belousov–Zhabotinsky (BZ) solutions
infiltrated in cellulose paper filters. Exhausted supports can be reactivated many times by
adding new BZ medium. Different parameters can be independently controlled to program
mono-or multipaced information storage.
