  • Patent number: 8696812
    Abstract: Thin films of ferroelectric material with a high mole fraction of Pb(A2+1/3B5+2/3)O3 substantially in a perovskite phase, wherein A is zinc or a combination of zinc and magnesium, and B is a valence 5 element such as niobium or tantalum, have been prepared. Typically, the mole fraction of Pb(A2+1/3B5+2/3)O3 in the ferroelectric material is >0.7. The method for preparing the thin films of ferroelectric material comprises providing a precursor solution containing lead, A2+, and B5+; modifying the precursor solution by addition of a polymer species thereto; applying the modified precursor solution to a surface of a substrate and forming a coating thereon; and (d) subjecting the coating to a heat treatment and forming the film in the perovskite phase. Optimal results have been obtained with PEG200 as the polymer species.

  • Publication number: 20090263671
    Abstract: Ferroelectric Poly(vinylidene fluoride) Film on a Substrate and Method for its Formation A method of producing a poly(vinylidene fluoride) (“PVDF”) film on a substrate from a precursor solution is disclosed. The method comprises preparing the precursor solution for the PVDF film and dissolving an additive in the precursor solution, the additive being selected from the group consisting of: a hydrate salt, and a hygroscopic chemical. The PVDF is added to the precursor solution. The PVDF solution is coated on a substrate to form an as-deposited PVDF film which is dried and crystallized at an elevated temperature. The dried and crystallized as-deposited PVDF film is annealed at a further elevated temperature. The further elevated temperature is greater than the elevated temperature but less than a melting point of the as-deposited PVDF film. The additive dehydrates at the further elevated temperature. A corresponding product is also disclosed.

  • Publication number: 20090155877
    Abstract: A biochip (100) for lysing and/or cell separation is formed to provide a sealed chamber for biological fluid. A conductive layer (140) bonded between upper (130) and lower (150) insulating layers is etched to form a microfluidic channel (250) between two electrodes (190, 200). The microfluidic channel connects a fluid inlet (11) and fluid outlet (120). The electrodes (190, 200) form an un-even electric field in the channel (250) to generate a dielectrophoretic force on the cells/particles within the sample fluid. A voltage source applies a suitable voltage to separate and/or lyse cells within the fluid.
