Different functions on samples (on a surface or in channels)

Two kinds of acousto-fluidic interactions :

  • Low frequency (<100 kHz) standing waves
    • Flexural plate waves
    • Step by step displacement
  • High frequency travelling waves
    • Surface acoustic waves (SAW)
    • Acoustic streaming
    • Linear and step by step displacement.

Applications to droplets

Droplet displacement due to
stationary wave commutation
Nebulize droplet Droplet displacement using SAW
Particles in droplets (100µm)

Acoustic Mixing of a matrix of
droplets with a biochip

Droplet race
Mixing activation Merging droplets Liquid jets
