Abstract Signal drift and hysteresis of flexible piezoresistive sensors pose significant challenges against the widespread applications in emerging fields such as electronic skin, wearable equipment for metaverse human‐AI (artificial intelligence) interfaces. To address creep relaxation issues associated with pressure‐sensitive materials, a highly stable composite is proposed, using polyamide‐imide (PAI) fibers matrix situ grafted‐polymerized polyaniline (PANI) semi‐conducting layer. The PAI large rigid fluorenylidene groups exhibits high glass transition temperature 372 °C (PAI 5‐5), which results an extremely long time at room consequently offers outstanding anti‐creep/relaxation performances. enhancement PAI‐PANI interfacial bonding through grafting improves sensor reliably. presents linear sensitivity 35.3 kPa −1 over pressure range 0.2–20 kPa, repeatability, excellent dynamic stability only 3.8% signal deviation ≈10 000 cycles. Real‐time visualization distribution realized by matrices, demonstrate capability tactile gesture recognition on both flat curved surfaces. sitting postures achieved two 12 × matrices facilitated machine learning, prompts potential augmentation smart driving.

Storage and analysis of large-scale risk-monitoring time series data is essential for the preventive conservation cultural heritage sites. However, as this monitoring accumulates to large scales, traditional relational databases can face serious performance bottlenecks, such high latency when writing from multiple sensors, inefficient retrieval. These problems significantly hinder risk data. To address these issues, we propose a software architecture management platform geared towards The includes bus layer, computing engine storage visualization cluster high-availability services layer. function each layer described, well strategy persistence key business pipelines. Next practical test, use open-source build pilot system Mogao Grottoes, world site in Gansu, China. We select system’s parameters based on comparisons, then demonstrate implementation its functions sensor integration, alerts, interpretation. results show that handle high-volume concurrent insertion, management, long-term historical operations. This proposed serve reference those constructing platforms other sites museums.

Inspired by the structure of Setaria viridis and based on guidance molecular dynamics simulations, a hierarchical nanospike micrometer-sized coaxial fibers has been designed at scale. A piezoresistive composite membrane in situ-grown PDA-PPy TPU@PES fiber prepared, exhibiting good anticreep performance, high sensitivity, fast response. The matrix material is as fibers, which consist an inner PES core that provides mechanical support outer thermoplastic polyurethane shell offers large specific surface area rich graft reaction sites. semiconductor phase constructs interlocking structured forming multihierarchical conducting network. sensor constructed with this exhibits ultrahigh sensitivity (27.1 kPa-1) quick response (23.1 ms time 26.3 recovery time). Furthermore, chemical grafting process ensures stable interface between creating covalent hydrogen bonds. This not only prevents instability but also demonstrates excellent signal performance dynamic stability (10,000 cycles). Monitoring changes renal pelvic pressure 3D-printed artificial pelvis was performed, confirming its practicality for medical monitoring.
