The fabrication was performed in clean room using standard machining process using an oxidized silicon (100)
wafer. Afterwards, the different parts were assembled. The PZT was glued to the membrane back side using a non
conductive glue (Loctite 480), then connected to the excitation electrodes by wire bonding technique using a gold
wire of 50 μm in diameter, in order to connect electrodes with electric connector a conductive glue (loctite 3880)
was used. Finally the fluidic connectors were stuck against the fluidic holes; see Fig 1(b).
