Lightweight, low‐cost metasurfaces and reflectarrays that are easy to stow and deploy are desirable for many terrestrial and space‐based communications and sensing applications. This work demonstrates a lightweight, flexible metasurface platform based on flat‐knit textiles operating in the cm‐wave spectral range. By using a colorwork knitting approach called float‐jacquard knitting to directly integrate...
The investigation of lead‐free ceramics with exceptional piezoelectric properties holds great importance in the substitution of lead‐based materials, hence promoting the development of green technology and fostering an environmentally sustainable society. This study successfully synthesized two series of Bi(Mg2/3Nb1/3)O3 (BMN)‐modified BiFeO3–BaTiO3 (BF–BT) lead‐free piezoelectric ceramics using the...
