Abstract Electronic skin (e‐skin) has been under the spotlight due to great potential for applications in robotics, human–machine interfaces, and healthcare. Meanwhile, triboelectric nanogenerators (TENGs) have emerging as an effective approach realize self‐powered e‐skin sensors. In this work, bioinspired TENGs sensors are developed their robotic tactile sensing also demonstrated. Through facile replication of surface morphology natural plants, interlocking microstructures generated on...
Abstract Traditional human emotion recognition is based on electroencephalogram (EEG) data collection technologies which rely plenty of rigid electrodes and lack anti‐interference, wearing comfort, portability. Moreover, a significant distribution difference in EEG also results low classification accuracy. Here, on‐skin biosensors with adhesive hydrophobic bilayer hydrogel (AHBH) as interfaces for high accuracy are proposed. The AHBH achieves remarkable adhesion (59.7 N m −1 ) by combining...
Abstract Electronic‐skin (E‐skin) has been investigated extensively for robotic tactile sensing. However, E‐skin sensors based on flexible metamaterials are still challenging to achieve.

Deep‐sea exploration remains a challenging task as the extreme hydrostatic pressure environment, darkness, and suspended sediment launch severely hinder capability of deep‐sea vehicles. As complement to underwater camera, tactile perception becomes especially important in situations where machine vision is limited. However, sensors utilized deep sea, which should be able detect changes only hundreds pascals under high pressure, are still lacking. To tackle challenge imposed by simulated...
