Abstract: A biometric input system for an electronic device is provided. The biometric input system may be a fingerprint sensing system. The biometric input system includes a biometric sensing component, which may be a capacitive sensing component. The biometric input system also includes a composite cover element, which may be a dielectric cap or coating, and the biometric sensing component is capable of receiving a biometric input from a user through the composite cover element. Electronic devices including the biometric input system are also provided.

Abstract: The present invention provides a biomimetic agent for anti-biofouling networks and application thereof. The antibiofouling networks have a mole mass ratio of poly(vinylpyrolidone) to poly(sulfobetaine methacrylate) in a range of 70/30˜42/58 and are derived from a copolymer comprises poly(vinylpyrolidone)-block-poly(sulfobetaine methacrylate), poly(vinylpyrolidone)-random-poly(sulfobetaine methacrylate) and poly(vinylpyrolidone)-alternating-poly(sulfobetaine methacrylate).

Abstract: The present invention provides a biomimetic agent for anti-fouling coating and a method for making the same. The biomimetic agent comprises a block, random, or alternating copolymer having a general formula (1): AUnBUm, where AU represents a repeating unit comprising an anchoring moiety, BU represents a repeating unit comprising a zwitterionic moiety or a pseudo-zwitterionic moiety, m is an integer of 5˜120 and n is an integer of 5˜120.

Abstract: This invention discloses an anti-biofouling membrane for water-treatment. The anti-biofouling membrane for water-treatment comprises a substrate, and an anti-biofouling copolymer on the substrate. The anti-biofouling copolymer comprises a plurality of hydrophobic groups and a plurality of hydrophilic groups. The anti-biofouling copolymer can be stably coated on the surface of the substrate by the hydrophobic groups. And the hydrophilic groups can help the anti-biofouling membrane to present excellent anti-biofouling capability. Preferably, the anti-biofouling copolymer coated on the substrate will not decrease the permeability of the substrate. More preferably, the presented capability of the mentioned anti-biofouling membrane for water-treatment can achieve the commercial level filtering membrane.
