Device for manipulating droplets through ultrasound KU Leuven
A device (1) for manipulating a droplet (2) comprising water, the device (1) comprising:a surface (10) configured to support the droplet (2), the surface (10) comprising a hydrophobic region (12);an ultrasound transducer array (20), the ultrasound transducer array (20) being arranged above the surface (10), and separated from the surface (10); wherein the ultrasound transducer array (20) is configured to emit ultrasound for actuating a motion of the droplet (2) along the surface (10) by subjecting the droplet (2) to an acoustic radiation force by the emitted ultrasound.
