Abstract
We demonstrate droplet manipulation using electric signals to induce the liquid to wet or dewet on a hydrophilic conductive substrate in the air without adding layers. In this phenomenon, the contact angle changes more than 15{\deg} or -20{\deg} by using the ionic surfactant mediated droplets, with only \pm3 volts of the actuation voltage.
