Abstract High spatial‐resolution detection is essential for biomedical applications and human‐machine interaction. However, as the sensor array density increases, miniaturization will lead to interference between adjacent units deterioration in sensing performance. Here, inspired by cochlea's structure, a high‐density flexible pressure featuring with suspended membrane sensitivity‐enhanced customized channels presented crosstalk‐free high‐resolution detection. By imitating basilar attached spiral ligaments, fixed onto high‐stiffness substrate cavities, forming stable braced isolation provide an excellent capability (crosstalk coefficient: 47.24 dB) integration (100 within 1 cm 2 ). Similar opening of ion hair cells, wedge‐type expansion embedded cracks introduced stress concentration structures enables high sensitivity (0.19 kPa −1 ) large measuring range (400 kPa). Finally, it demonstrates promising distributed displays condition monitoring medical‐surgical intubation.

The advancement of intelligent and biodegradable respiratory protection equipment is pivotal in the realm human health engineering. Despite significant progress, achieving a balance between efficient filtration monitoring remains great challenge, especially under conditions high relative humidity (RH) airflow rate (AR). Herein, we proposed an interfacial stereocomplexation (ISC) strategy to facilitate intensive polarization for poly(lactic acid) (PLA) nanofibrous membranes, which were customized machine learning-assisted diagnosis. Theoretical principles underlying facilitated formation electroactive phase aligned PLA chains quantitatively depicted ISC-PLA nanofibers, contributing increased dielectric constant surface potential (as as 2.2 5.1 kV, respectively).
