The output performance of triboelectric sensors (TESs)
still encounters
some limitations, such as interface charge recombination and incomplete
contact during deformation. This study improves the performance of
TESs by integrating material interface engineering with structural
design. A 1-mm-thick hydrogel generates the strongest interfacial
polarization electric field, reducing the charge recombination rate
from 25.6% to 4.1%. Meanwhile, optimizing the hydrogel thickness improves
structural compliance and enlarges the effective contact area. Therefore,
a 3-mm-thick hydrogel achieves the maximum surface charge density
of 219 μC·m<sup>–2</sup> by balancing charge-recombination
suppression and effective contact status. Additionally, the spacer
gap of TES is optimized to regulate contact evolution during deformation,
consistent with the Föppl–von Kármán large-deflection
model. The combined theoretical and experimental analyses clarify
the roles of interfacial polarization and structural deformation in
output enhancement. The optimized TES further enables sitting-posture
recognition, demonstrating its potential for health monitoring.
