Abstract

A neck pillow includes: a cushion portion worn on a user's neck and an electro-liquid driving unit mounted into the cushion portion, being bent in a shape of an arc, and including ferroelectric particles, each having an electrorheological property, and nonconductive liquid. The electro-liquid driving unit generates vibration by contraction and expansion that are repeated when an arrangement of the ferroelectric particles and the nonconductive liquid is changed according to whether drive current is applied. A low voltage power supply unit supplies low voltage electricity necessary to drive the electro-liquid driving unit and a high voltage control circuit unit converts low voltage direct current into high voltage direct current and supplies the drive current to the electro-liquid driving unit and adjusting micro-current to generate target vibration in the electro-liquid driving unit.
