Abstract
A biopatch, a bioheater, a biosensor and a bioelectronic patch device are provided.The biopatch comprises a polymer film comprising a biopolymer and a drug loaded in the polymer film. The biopolymer may comprise one or more than one of a bioabsorbable polymer, a biodegradable polymer and a biocompatible polymer. The biopolymer may comprise oxidized starch. The drug may comprise a first drug chemically combined with the oxidized starch and a second drug physically combined with the oxidized starch.The bioheater comprises a heater comprising biometal. The biometal may comprise Mg or Fe. The heater can be controlled wirelessly by an alternating magnetic field.A biosensor according to one embodiment of the present inventive concept comprises an inductor and a capacitor connected to the inductor, wherein the capacitor comprises a first electrode, a second electrode facing the first electrode and a dielectric disposed between the first electrode and the second electrode, each of the inductor, the first electrode and the second electrode comprises biometal, and the dielectric comprises a biopolymer having a glass transition temperature in a range of 36˜42° C. A biosensor according to anot…
