Hydrophones play a crucial role in underwater target detection within sonar systems. However, existing hydrophones often encounter challenges such as low sensitivity and poor signal-to-noise ratio (SNR) the of low-frequency acoustic signals. This work introduces capacitive hydrophone (CH) designed for highly sensitive sound Comprising latex film/silver electrode structured hydrogel electrolyte layer, CH is enclosed cylindrical casing. By strategically integrating carbon nanotube (CNT) topology network pyramid microarray hydrogel, sensor efficiently forms electric double layer (EDL), enhancing precision. The showcases exceptional low-pressure across wide frequency spectrum (20 to 800 Hz), achieving receiving up -159.7 dB critical band 125 surpassing performance commercial (RHC-14) by substantial margin 33.29 dB. Furthermore, maintains superior SNR, enabling waves faint 0.3 Pa. study demonstrates capabilities detecting maritime vessels sounds, underscoring potential CNT-enhanced EDL sensing mechanism future design.

Flexible skins that can be laminated on curved surfaces are a desired form for wind pressure measurement. Sensors such applications need to detect both negative and positive with ultrahigh resolution over wide range up 600 kPa, whereas existing flexible sensors unsatisfactory demands. Here, we report skin containing two iontronic sensing, respectively, show the potential of measurement in room temperature tunnels. We control contact state interface sensor introduce pre-pressure enables exhibiting -20 Pa (0.025%) within broad regime (from -100 kPa -10 Pa). The other sensing exhibits pressure-resolution 100 addition frequency bandwidth 400 Hz. types attached wing surface at various free stream velocities angles attack. This study provides promising technology using aviation applications.

Industrial robots are the main piece of equipment intelligent manufacturing, and array-type tactile sensors considered to be core devices for their active sensing understanding production environment. A great challenge existing is wiring units in a limited area, contradiction between small number high resolution, deviation overall output pattern due difference performance each unit itself. Inspired by human somatosensory processing hierarchy, we combine with artificial intelligence algorithms simplify sensor architecture while achieving resolution capabilities far greater than signal channels. The prepared 8-electrode carbon-based conductive network achieves high-precision identification 32 regions 97% classification accuracy assisted quadratic discriminant analysis algorithm. Notably, remains unchanged after 13,000 cycles at 60 kPa, indicating its excellent durability performance. Moreover, large-area skin-like continuous simple fabricate, cost-effective, can easily scaled up/down depending on application. This work may address increasing need fabrication, rapid integration, adaptable geometry use industrial robots.
