Additive manufacturing (AM) technology has recently seen increased utilization due to its versatility in using functional materials, offering a new pathway for next-generation conformal electronics the smart sensor field. However, limited availability of polymer-based ultraviolet (UV)-curable materials with enhanced piezoelectric properties necessitates development tailorable process suitable 3D printing. This paper investigates structural, thermal, rheological, mechanical, and newly developed resin material. The polymer is based on polyvinylidene fluoride (PVDF) as matrix, mixed constituents enabling UV curability, boron nitride nanotubes (BNNTs) are added form nanocomposite resin. results demonstrate successful micro-scale printability resins liquid crystal display (LCD)-based printer. Additionally, incorporating BNNTs into matrix properties, an increase voltage response by up 50.13%. work provides insights printable flexible devices energy harvesting systems.

Gas pipeline leakage will result in casualties and property losses if not detected time. Conventional localization methods usually rely on dense grid distribution, leading to high computational costs. This study proposes a time-reversal-based adaptive generation approach enhance efficiency localization. The method introduces resolution adjustment parameter optimize captured signals, allowing for concentration areas based energy distribution. Based this principle, three steps—including signal computation, conventional TR computation the grids—are introduced. Then, an experimental is conducted 55.8 m PVC with piezoceramic transducers, capturing negative pressure wave signals from four points. results demonstrate that proposed maintains comparable accuracy while reducing number of grids time only 0.6% 2.4% those required by uniform methods, respectively. findings offers computationally efficient accurate solution real-time monitoring.
