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° or -20° by using the ionic surfactant mediated droplets, with only ±3 volts of the actuation voltage.
