With the rapid advancement of electronic skin and wearable health-monitoring technologies, flexible sensors are evolving from single-parameter detection towards the synergistic sensing of multiple parameters, such as temperature, pressure, and physiological signals. Conventional multi-parameter devices typically require the integration of distinct sensing units alongside independent electrodes and signal transmission lines; this often results in complex device architectures, cumbersome manufacturing processes, and limited system integration. In contrast, functional materials exhibiting both thermoelectric and piezoresistive effects can independently distinguish between temperature and pressure by utilising voltage changes induced by temperature gradients and resistance changes caused by external forces, respectively, offering the potential to simplify device structures while enhancing multi-parameter sensing capabilities.

Persistent inflammation and oxidative stress can reinforce each other, damaging oral tissues and hindering repair. A new review examines how tetrahedral framework nucleic acids—tiny, programmable DNA structures—could both neutralize harmful reactive oxygen species and deliver therapeutic molecules to affected tissues. Promising laboratory and animal studies point toward future approaches for periodontal disease, jawbone damage and oral mucosal disorders, although major challenges remain before clinical use.

Electrically conductive composite ceramics face a trade-off between electrical conductivity and densification. Herein, a bimodal micro/nano particle size grading strategy is proposed to resolve this issue in the Al₂O₃–TiC system. Nano-Al₂O₃ fills interparticle spaces and pins TiC grain boundaries, while micro-Al₂O₃ coarsens, enlarging the phase domain size ratio and forming continuous 3D TiC networks. At a nano-Al₂O₃ content of 10 vol% , the composite reaches 99.02% relative density and a conductivity of 4.02 × 10⁴ S/m , with the percolation threshold reduced from 15.54 to 10.20 vol%. EDM performance is also enhanced, offering a promising route for machinable conductive ceramics.
