Abstract: The present invention relates to a biosensor for inspecting the susceptibility of a microorganism to an antibiotic, a fabrication method therefor, and a method for inspecting the susceptibility of a microorganism to an antibiotic by using same, wherein the biosensor comprises: a substrate including polyethylene terephthalate; and a sensor part formed on one surface or both surfaces of the substrate and comprising an electrode inclusive of a first electrode and a second electrode which interdigitate with each other.

Abstract: Provided is an air charging apparatus driven by a rotating magnetic field and compressing or pressurizing and transferring air. The air charging apparatus includes at least one impeller sucking air and giving kinetic energy to intake air; an impeller case leading external air inhaled by the impeller into the impeller and converting velocity energy of air out of the impeller into air having pressure energy to discharge air; and a rotating body accelerator equipped with the impeller and the impeller case and driving the impeller. Here, the rotating body accelerator drives the impeller by generating a torque by interaction with an intake negative pressure, by generating a torque by interaction with the intake negative pressure and using supplied power, or by generating a torque using supplied power.
