With
the rapid development of flexible electronics and intelligent
robotics, highly sensitive tactile sensing systems have become crucial
for human–machine interactions and object recognition. However,
achieving high sensitivity and mechanical robustness simultaneously
remains a major challenge. Herein, we develop a topological interface
engineering strategy to construct a polymer hydrogel with a multiscale
topological architecture via the competitive regulation of interfacial
hydrogen bonding. The resulting gel exhibits excellent mechanical
adaptability with high compressive strength (417 kPa) and tensile
strength (4.9 MPa). Under compression, confined ions within the topological
channels undergo nonuniform migration and localized enrichment, inducing
polarization effects that enhance the interfacial charge storage and
separation. The triboelectric tactile sensor achieves a sensitivity
of 6.278 V kPa<sup>–1</sup> and rapid response/recovery times
of 125/84 ms, enabling self-powered human–machine interaction
and object recognition. This work provides a new structural design
paradigm and a mechanistic regulation strategy for intelligent tactile
sensing systems.
