Abstract Underwater sensing is crucial for sea exploration and guiding underwater vehicles. Artificial flexible or soft sensors with high sensitivity environmental adaptability can be one promising alternative. However, the current may experience sharp decline of sensory performance attributed to heavy water pressure. Here, inspired by structure swimming bladder, a fish‐like dual‐bubbling membrane developed undiminished designing integrated actuation system mechanical sensing. The includes morphing layer elastomer 3D harder embedded carbon nanotubes (CNTs), capable detecting fluctuations as small 5 Pa at 8 kPa pressure maintaining stable up 18 kPa. rational design modular‐actuation (MASS) allows adjustment capability handle higher applied Furthermore, designed sensor into vehicle sensitively detect navigation behaviors further monitor external stimuli even under 1.6 m condition. proposed principle expected provide guidance biomimetic actuating systems.

Hydrogels have attracted increasing attention in wearable sensors, but preparing underwater hydrogel sensors with excellent anti-swelling and self-healing properties is still challenging. Herein, an prepared by grafting poly(acrylic acid) hydrophobic lauryl methacrylate, as well constructing a second network multiple molecular interactions (abbreviated PALCF). The introduced long alkyl chains the increased cross-linking density of result swelling ratio only 0.04% after immersion water for 15 days. Due to abundant metal coordination hydrogen bonds, PALCF exhibits high tensile stress 0.60 MPa efficiency reaching 96.0% at 60 °C 2 min. Based on piezoresistive effect, directly used strain sensor sensitivity (GF = 2.24) control vehicles rescue implementation. Furthermore, two self-powered triboelectric nanogenerator contact non-contact models are constructed based hydrogels communication, capable sending out SOS messages drowning alarms emergency. proposed warning rescuing functions potential use prevention, human-machine interfaces, communication system.

Abstract Ocean wave energy represents a widely distributed and abundant clean, renewable source. However, its efficient harnessing remains challenge. In this study, triboelectric‐electromagnetic hybrid generator of Ferris‐wheel‐like structure (FWS‐TEHG) with magnetic repulsion assistance is proposed to effectively enhance the collection low‐frequency low‐amplitude water energy. The Ferris‐wheel shell internal rotator are designed phase difference heighten swing amplitude, while introduction augments motion frequency. device has demonstrated excellent performance in conditions, from laboratory ocean tests. Operating at frequency 0.5 Hz angle 12° on six‐freedom platform, it lights up 64 LEDs power rating 2 W. Triggered by simulated waves 1 Hz, FWS‐TEHG charges 19 mF capacitor an average charging rate ≈0.58 W h −1 , powering water‐level alarm. oceanic harvests exhibiting output approximately four five times higher than that primary waves, thus enabling electrical devices such as temperature–humidity meters efficiently. This study provides valuable reference for advancing practical application nanogenerators natural environments.
