Classification: CPC G | IPC G  H

Claim 20:
21. A method comprising:
providing an activation signal for activating a first microfluidic device of a plurality of electrically-connected microfluidic devices embedded within first and second layers of a substrate, the first microfluidic device including:
an inlet port for supplying a fluid into the first microfluidic device,
a tube for receiving the fluid from the inlet port, and
a piezoelectric actuator; and

electrically actuating the piezoelectric actuator based on the activation signal for controlling an amount of the fluid supplied to the tube via the inlet port to realize a displacement of a portion of the first layer or the second layer of the substrate, the portion corresponding to an area of the substrate where the first microfluidic device is arranged and the displacement being based on the amount of the fluid or a pressure in the tube.
