Abstract: Frequent replacement of a battery is avoided even if power consumption is large, and the structure is simplified and waterproofness is improved. Furthermore, cost reduction is achieved because driving components are selectable from components with variously different operating voltages. A hearing aid includes a secondary battery having a nominal voltage higher than a nominal voltage of an air battery, driving components driven by power at different voltages supplied from the secondary battery, and a transformation unit configured to output the charging power of the secondary battery at a voltage suitable for driving each driving component.

Abstract: A wireless power transmission apparatus which is charged in a short charging time and prevents the shortening of the life of a secondary battery is provided. A wireless power transmission apparatus includes a current-voltage detector configured to measure an input impedance Zin of the wireless power transmission apparatus including the power-supplied device and a control device configured to determine whether a constant current charging period (CC) is finished by utilizing a change in the input impedance Zin measured by the current-voltage detector and terminate the charging of the lithium ion secondary battery when it is determined that the constant current charging period (CC) is finished.

Abstract: An arrangement place for a device such as a rectifier and a power storage device is easily secured. At the time of power supply using a resonance phenomenon, a power-receiving device generates a magnetic field space having a lower magnetic field strength than other parts at or around the inner side of the power-receiving module, and this magnetic field space is used as the arrangement place of an electronic component. The power-receiving module includes a power-receiving resonance coil which is resonated with a power-supplying module and a power-receiving coil which partly overlaps the power-receiving resonance coil in a coil diameter direction and receives and supplies power from and to the power-receiving resonance coil.

Abstract: A power-supplying resonator of a power-supplying module and a power-receiving resonator of a power-receiving module are arranged to face each other. On inner circumferential surface sides of the power-supplying resonator and the coil of the power-receiving resonator, cylindrical magnetic members which cover the entire inner circumferential surface of the coils of the power-supplying resonator and the power-receiving resonator are arranged. By conducting power transmission between the power-supplying resonator and the power-receiving resonator while varying a magnetic field, the magnetic field occurring around the power-supplying resonator and the power-receiving resonator is shielded by the magnetic members, and there is formed, on the coil inner circumferential surface sides of the power-supplying resonator and the coil of the power-receiving resonator, a magnetic field space whose magnetic field strength is smaller than the magnetic field strength of areas other than the inner circumferential surface sides.
