Abstract Constructing hydrogels with spatially heterogeneous structures are crucial for unlocking novel applications. To this end, selectively removing a specific portion of by facile and intricate destructive strategies is worth exploring. Herein, “contact‐destructive” hydrogel actuator presented, composed dynamic network doped hydrophilic polyethylene glycol (PEG). The behavior the attributed to surface tension‐induced spreading effect enhanced water absorption due additive PEG. Parameters that act on these mechanisms used control destruction hydrogel. During process, exhibits locomotion routes predetermined graphic pattern aid 3D printing. Additionally, such self‐destructive can be terminated UV light irradiation when PEG replaced poly(ethylene glycol) diacrylate (PEGDA). Significantly, diverse applications including controllable collapse, self‐erasing, on‐demand cell release, realized These results demonstrate present has great values in soft robotics, anti‐counterfeiting, controlled drug delivery, other related fields.

Hydrogel-based flexible electronic devices have great potential in human motion monitoring, skins, and human-computer interaction applications; hence, the efficient preparation of highly sensitive hydrogel-based sensors is important. In present work, ultrafast polymerization a hydrogel (1–3 min) was achieved by constructing tannic acid (TA)-Fe3+ dynamic redox system, which endowed with good adhesion performance (the strength wood 17.646 kPa). addition, uniform dispersal ensured incorporating polydopamine-decorated polypyrrole (PPy@PDA) into matrix significantly improved hydrogel’s stretching ability (575.082%). The as-prepared PAM/CS/PPy@PDA/TA sensor had high-fidelity low detection limit (strain = 1%), high sensitivity at small strains (GF 5.311 strain 0–8%), fast response time (0.33 s) recovery (0.25 s), it reliably applied to accurate monitoring handwriting recognition. opens new horizons for wearable devices, applications.
