Figure 1. SAW device consisting of 10 pairs of inter-digitated electrode on a sectioned piezoelectric lithium niobate wafer.

Figure 1

The width of each electrode was ~100μm, fabricated with a pitch of 200μm to provide a surface acoustic with a wavelength of 400μm. The aperture the IDT was 10mm. The IDT was excited at it’s resonance frequency of ~ 9.56MHz in a pulse mode where surface acoustic waves were radiated for a 20ms period of a 50ms duty cycle, the power used was 2W, nebulization was achieved under these conditions. .
