Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing
Advanced Materials Technologies, EarlyView.Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the
