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.

Abstract Electronic skin (e‐skin) capable of acquiring environmental and physiological information has attracted interest for healthcare, robotics, human–machine interaction. However, traditional 2D e‐skin only allows in‐plane force sensing, which limits access to comprehensive stimulus feedback due the lack out‐of‐plane signal detection caused by its 3D structure. Here, a dimension‐switchable bioinspired receptor is reported achieve multimodal perception exploiting film kirigami. It offers (pressure bending) (force airflow) signals dynamically inducing opening reclosing sensing unit. The receptor's hygroscopic thermoelectric properties enable humidity temperature. Meanwhile, can differentiate mechanical stimuli from temperature voltage. development enables wide range sensory capabilities expands applications in real life.

Abstract With the development of modern medicine, importance continuous and reliable pulse wave monitoring has increased significantly in physiological evaluation disease diagnosis. Among them, 3D reconstruction is indispensable, needs rely on ultra‐high resolution sensor arrays, that is, high spatial resolution, temporal force resolution. Herein, a flexible high‐density 32 × tactile array based pressure‐sensitive tunneling mechanism develpoed. Conformal graphene nanowalls ( GNWs ) pattern arrays are deposited micro‐pyramidal structural Si substrate via mask‐assisted plasma enhanced chemical vapor deposition PECVD) method adopted as electrode, exhibiting 64 dots/cm 2 , sensitivity (222.36 kPa −1 short response time (2 ms). More importantly, HfO layer can effectively suppress noise current, which made it sense weak pressure signals with 1/1000 SNR 36.32 dB. By leveraging its high‐resolution array, more holistic acquired shape successfully replicated. This work shows sensors have significant promise for applications remote intelligent diagnostics.
