  • Publication number: 20170252227
    Abstract: A wetness sensor includes a self-supporting substrate and an electrically conductive trace carried by the substrate. The trace is patterned to provide at least a portion of a tuned RF circuit, which may be disposed on only one side of the substrate and characterized by an impedance or resistance. The trace is not self-supporting. The substrate is adapted to dissolve, swell, or otherwise degrade when contacted by a target fluid. Such degradation produces a drastic change in the operation of the RF circuit, which can be interpreted by a remote reader as a “wet” condition. Contact of the substrate by the target fluid may change the impedance or resistance of the RF circuit by at least a factor of 5, 10, 100, or 1000, and/or may cause the trace to disintegrate so as to provide the RF circuit with an open circuit, and/or may substantially render the RF circuit inoperative.

  • Patent number: 9078946
    Abstract: A method of treating porous particles, each porous particle having an external surface and a multiplicity of pores with interior pore surfaces, by contacting the external surface with a hydrophobic agent while causing the interior pore surfaces to remain substantially free of the hydrophobic agent. In certain illustrative embodiments, treating the external surfaces of the porous particles includes exposing the porous particles to at least one of water vapor, methanol vapor, or ethanol vapor; and subsequently exposing the porous particles to a second vapor comprising a reactive organosilane compound which reacts to form the hydrophobic agent. In some particular illustrative embodiments, at least a portion of the external surface of the treated porous particle includes hydrophobic groups, the hydrophobic groups selected from at least one of alkyl or aryl groups optionally substituted with fluorine, and siloxanes having alkyl groups, aryl groups, or combinations thereof.
