SELECTIVE WET CHANNELS FOR WATER DRAINAGE PPLICATIONS
This abstract first appeared for US patent application 18335642 titled 'SELECTIVE WET CHANNELS FOR WATER DRAINAGE PPLICATIONS
Original Abstract Submitted
A method for water drainage of a substrate includes creating, on a surface of the substrate, a designated hydrophobic region having hydrophobic surfaces of a hydrophobic film. Electronic circuitries are fabricated in the designated hydrophobic region of the substrate. The method further includes creating, on the surface of the substrate, a designated hydrophilic region having hydrophilic surfaces of the substrate. A drainage channel is formed in the designated hydrophilic region. The method further includes facilitating, based on capillary imbibition of the drainage channel, fluid flow from the designated hydrophobic region to a drainage/evaporation port to prevent damage of the electronic circuitries by moisture accumulation in the designated hydrophobic region.
