Abstract
A study using optical high speed imaging shows that droplet dynamics and contact times of water droplets impacting vibrating superhydrophobic surfaces depend on the vibration frequency, phase at impact, and amplitude of vibration. Contact times can be greater or smaller than the theoretical contact time on a nonvibrating surface.
