Abstract

Static wetting morphologies in grooves with triangular cross section are studied here. Using the electrowetting effect, we can switch between different equilibrium morphologies and transport liquid along prefabricated grooves. The particular filling and drainage behavior in triangular grooves is discussed in terms of the groove geometry.
