Three-dimensional-printed complex mullite structures based on triply periodic minimal surfaces (TPMSs, namely, Schwartz and Gyroid) with two different thicknesses (Schwartz 1 Gyroid 1–4 mm, 2 2–6 mm) were fabricated tested as humidity sensors. The samples sintered at 1450 °C in the range from 0% to 89% relative (RH) room temperature evaluate effect of geometry thickness sensitivity. After water vapor exposure temperature, response was 2.84 under 89 RH% for structure (1.36 structure) 1.21 (7.00 structure). results showed that, RH, best sensors achieved structure. Sensors exhibit good repeatability, there no interference presence other gases.

Abstract Given the electrical signal transduction capability and excellent biocompatibility, conductive hydrogels are regarded as ideal candidates for high‐performance strain/pressure sensors applied in personalized medicine. However, there challenges concurrent attainment of flexible hydrogel‐based with remarkable conductivity, sensitivity, reliable stability. Herein, a synergistic strategy based on hole–bridge structure molecular‐crowding effect is proposed to fabricate multifunctional sensor. As‐prepared eutectic hydrogel displays comprehensive performances impressive conductivity (2.81 S m −1 ), boosted mechanical robustness (a tensile strength 2.95 MPa), environmental tolerance (≈79.8% water retention at 50 °C 20 days; frost resistance = −45.3 °C). Notably, hydrogel‐derived stretchable sensor effective antibacterial ability exhibits enhanced sensitivity (gauge factor 4.49) across wide linear range, supporting monitoring joint movement electrocardiographic signals, along on‐demand photothermal treatment. As demonstration, employment efficiently conveying information high‐fidelity handwriting recognition investigated assistance machine learning. This innovative holds high promise future applications wearable‐smart devices integrated wireless transmission modules, exhibiting great potential personal rehabilitation training healthcare monitoring.
