Hydrogen (H2) gas has great potential as an energy carrier in the emerging renewable market, emitting zero CO2. However, its high explosive and flammability pose substantial risk across production, storage, transport, consumption; thus, rapid detection of leaks is essential. In this research, hollow TiO2 nanospheres (h-TiO2 NS) with a mean diameter ∼216 nm are fabricated via solvothermal method. The NS were then chemically decorated Pd nanoparticles ∼3.0 (Pd/h-TiO2 NS). Pd/h-TiO2 enables permeation by H2, maximizing active sites due to their specific surface area ∼80 m2/g mesoporous structure average pore size 5.6 nm. chemiresistive sensor shows promising results toward H2 at 80 °C under 9 V bias 365 UV light exceptional response (4.1 for 0.1% ∼88 1% H2), time 36 s 76 fast recovery (38 39 respectively). Even dark conditions, exhibits (2.3 ∼47 H2) 52 efficient (68 Additionally, wide range concentrations from 50 10,000 ppm can be detected both conditions.

Wearable gas sensors offer remarkable advantages in terms of portability and real-time monitoring, rendering them highly promising for various applications such as environmental detection, health early disease diagnosis. However, the most widely used oxide semiconductor encounter substantial challenges achieving mechanical flexibility room-temperature detection due to their inherent rigidity, brittleness, reliance on high operating temperatures. Herein, an all-inorganic wearable sensor is fabricated by depositing anatase/rutile TiO2 (TiO2-A/R) homojunction a flexible yttria-stabilized zirconia (YSZ) nanofiber substrate using atomic layer deposition technology. The combination YSZ ultrathin sensing (∼13 nm) endows with tiny linear strains (0.55%) when subjected radius curvature 25 μm. As result, inorganic YSZ/TiO2-A/R can be folded multiple times without fracturing maintain stable electrical connectivity during cyclic bending. Furthermore, utilization photoactive homojunctions allows activated UV light operated at room temperature. efficient separation efficiency photogenerated carriers, which stems from interfacial electric field homojunctions, significantly enhances sensor's response, leading low limit 0.15 ppm acetone. In addition, was anchored mask successfully utilized simulated breathing diabetics; response signals demonstrate its potential noninvasive diabetes This study provides valuable reference advancement sensors, offering insights into
