Cover Picture: Remotely triggerable transient materials can couple on-demand functional reconfiguration with clean end-of-life control in soft systems. Here, we present a laser-addressable silicone elastomer composite that undergoes rapid thermochemical liquefaction under femtosecond laser pulses. The composite integrates Fe3O4 nanoparticles (Fe3O4 NPs) as photothermal transducers and diphenyliodonium hexafluorophosphate (DPI-HFP) powders as thermally activated fluoride generators, which catalyze Si-O bond cleavage. Localized photothermal heating initiates decomposition at moderate fluence and enables device-scale erasure under significantly lower energy input than direct laser ablation of pristine Ecoflex.

Back Cover Picture: Wearable electrophysiological interfaces demand bioelectrodes that combine low-impedance, stable ion-electron transduction with high mechanical deformability, yet these requirements remain fundamentally incompatible in existing systems. Here, we present a nonpolarizable stretchable dry electrode based on a bead-on-string Ag/AgCl heterostructure, in which AgCl nanoparticles (NPs) are selectively assembled along percolated silver nanowire networks embedded within an elastomer matrix. This architecture spatially decouples Faradaic reaction sites from conductive pathways, constructing abundant, mechanically robust Ag/AgCl heterointerfaces for efficient ion-electron transduction while preserving continuous electron transport under large deformation.
