Abstract

A liquid transfer device electrically controls liquid position. The surface of the liquid transfer device is provided with unevenness in order to solve a problem of having a large number of electrodes for controlling voltage. The number of electrodes for controlling voltage can be halved by the utilization of a restoring force of the liquid to a spherical shape by surface tension, in addition to an electrical force.
