Abstract:
1. A balance board comprising: a substrate; a first wire disposed on the substrate and to which a first power supply voltage is applied; a second wire disposed on the substrate and spaced apart from the first wire and to which a second power supply voltage having a substantially opposite phase to that of the first power supply voltage is applied; a plurality of first balance coils connected to the first wire and which uniformly distribute the first power supply voltage; a plurality of second balance coils connected to the second wire and which uniformly distribute the second power supply voltage; and a conductive pattern disposed on the substrate and spaced apart from the first and second wires, wherein the first and second wires are disposed substantially in parallel with each other along a long axis defining the substrate, the second wire being divided into a plurality of parts with respect to an area where the first wire and the second wire cross over one another, and the plurality of parts of the second wire are connected by a plurality of jumper connectors overlapping the first wire.
