  • Ceramic-based humidity sensitive material with liquid polymeric delivery vehicle
    Patent number: 12110407
    Abstract: A humidity sensitive material includes a lanthanum-doped barium titanate (BaTiO3) co-doped with an alkali hydroxide. A polymeric liquid binder is used as a vehicle to deliver the humidity sensitive material to a substrate or electrode via a 3D-printing process. The humidity sensitive material is highly sensitive to changes in humidity and exhibits rapid and large changes in capacitance and impedance for just a relatively small change in humidity. The humidity sensitive material exhibits significantly large changes in impedance and capacitance over the entire 10-90% RH range. As a result of the high sensitivity of the humidity sensitive material, the log-linear response is significantly easier to calibrate in humidity sensing devices that use the humidity sensitive material.
