Multifunctional modular electrospun fiber with heterogenous structure for multimodal sensing

• • The patterned cellular fibrous structure preserves sensing performance under 10% tensile strain, enabling strain-insensitive operation critical for wearable devices subject to deformation. • • The hybrid piezoresistive/piezoelectric platform detects both static pressure and dynamic acoustic stimuli across a frequency range of 0–300 Hz, covering typical human physiological and environmental signals. • • The sensor achieves a highest material identification accuracy of 98.6%, demonstrating superior discrimination capability for tactile sensing applications. • • Temperature-induced resistance drift is distinguishable via simultaneous analysis of resistance response profiles and thermoelectric output signals, enabling dual-parameter measurement without cross-talk.
