Here, an endogenous tribo-enhanced piezoelectric pressure sensing with visualization capability was developed by coupling a PAN/PVDF-HFP heterogeneous nanofiber membrane with a ZnS:Cu/PZT/Ecoflex electroluminescent layer. The nanofiber membrane features a skeleton-filling architecture in which PAN-rich and PVDF-HFP-rich domains create abundant heterogeneous interfaces for endogenous triboelectric charge generation. Incorporation of [BMIM]­[BF₄] further promotes charge separation and transport, increasing the open-circuit voltage and short-circuit current to 8 V and 22.8 nA, respectively. The enhanced electromechanical output directly drives the electroluminescent layer, enabling the real-time visualization of handwriting, patterned indentation, and dynamic stretching. This work provides an interface engineering strategy for self-powered visual pressure sensing. 2026-09-30T00:00:00Z Text Journal contribution 10.1021/acs.nanolett.6c03418.s001 https://figshare.com/articles/journal_contribution/Endogenously_Triboenhanced_Heterogeneous_Piezoelectric_Nanofiber_Membranes_for_Self-Powered_Electroluminescent_Pressure_Sensing/34032630 CC BY-NC 4.0
