Protocol

We establish here a method for coating the surface of a surface acoustic wave (SAW) device with amorphous Teflon film to improve the atomization efficiency required for application to an olfactory display.

Difficulty

advanced

Total time

~4–6 hours (including coating cure time and experimental runs)

Steps

Prepare and characterize surface acoustic wave device

Examine the lithium niobate SAW device substrate and understand its baseline properties before surface modification.

▶ 00:39

Silanize the device surface

Apply silanization treatment to the SAW device to prepare the surface for subsequent coating application.

▶ 01:13

Coat device with amorphous Teflon film

Deposit amorphous Teflon coating onto the silanized surface to reduce wetting and enhance atomization efficiency.

▶ 02:31

Set up atomization testing apparatus

Assemble the experimental setup for atomization testing, including liquid reservoir, acoustic excitation, and detection systems.

▶ 03:32

Execute atomization on coated device

Activate the SAW device and generate aerosol particles from liquid on the coated surface under controlled conditions.

▶ 04:40

Detect and measure scent dispersal

Use detection methods to validate that atomized scent particles are successfully generated and dispersed from the device.

▶ 05:47

Compare wetting and atomization performance

Analyze and compare atomization efficiency and surface wetting behavior between bare and Teflon-coated lithium niobate surfaces.
