NOVELTY - The method involves depositing a layer of a non-soluble polymer (4) on top of a layer of a soluble polymer, where the layer of the non-soluble polymer forms a flexible membrane (12). A thin-film electronic circuit i.e. bottom gate thin-film transistor (5), is formed on top of the flexible membrane to form an electronic chip, where the electronic chip is placed in solvent that dissolves the layer of the soluble polymer such that the flexible membrane with the thin-film electronic circuit is released to form the flexible electronic membrane.    USE - Method for fabricating a flexible electronic membrane i.e. highly bendable or stretchable thin and ultra-flexible electronic membrane, of an electronic device i.e. flexible thin-film electronic device, of an electronic contact lens (all claimed) i.e. plastic contact lens, for ophthalmic applications to measure intraocular pressure for monitoring glaucoma disease of a human. Can also be used for a rollable display, rollable keyboard, conformable sensor, flexible plastic solar cell and a flexible battery.    ADVANTAGE - The method enables providing a destination substrate e.g. polyimide foil substrate such as Kapton (RTM: polyimide film) foil substrate, with thickness of 50 micrometers that is dipped into solvent and moved beneath the electronic membrane and lifts the electronic membrane out of the solvent, thus avoiding curling of the electronic membrane and damaging of the layer of polyvinyl alcohol using only temperatures not exceeding 150 degree Celsius. The method enables fabricating the electronic membrane that is easy to implement with relatively high performance.
