“…The concept of fluid atomization using surface acoustic waves was already demonstrated by Kurosawa et al in 1995. 1,2 Since then, this phenomenon has been investigated in various scientific publications, regarding the underlying physical phenomena [3][4][5] or possible applications, including inhalation therapy, [6][7][8] olfactory displays, [9][10][11] micro-and nanoparticle synthesis, [12][13][14][15][16][17][18] thin film deposition 19,20 and mass spectroscopy of non-volatile fluids. [21][22][23][24] Despite the broad variety of attractive applications and previous work detailing the mechanisms of SAW atomization, still no commercial SAW-based fluid atomizer is available after 20 years of research.…”

SAW-based fluid atomization using mass-producible chip devices

Surface acoustic wave (SAW)-based fluid atomizers are ideally suited to generate micrometer-sized droplets without any moving parts or nozzles. Versatile application fields can be found for instance in biomedical, aerosol or thin film technology, including medical inhalators or particle deposition for advanced surface treatment. Such atomizers also show great potential for on-chip integration and can lead to economic production of hand-held and even disposable devices, with either a single functionality or integrated in more complex superior systems. However, this potential was limited in the past by fluid supply mechanisms inadequate for mass production, accuracy and reliability. In this work, we briefly discuss existing fluid supply methods and demonstrate a straightforward new approach suited for reliable and cost-effective mass-scale manufacturing of SAW atomizer chips. Our approach is based on a fluid supply at the boundary of the acoustic beam via SU-8 microchannels produced by a novel one-layer/double-exposure photolithography method. Using this technique, we demonstrate precise and stable fluid atomization with almost ideal aerosol plume geometry from a dynamically stabilized thin fluid film. Additionally, we demonstrate the possibility of in situ altering the droplet size distribution by controlling the amount of fluid available in the active region of the chip.

“…The authors evaluated the device and, akin to other works, found that a significant elevation in olfactory thresholds exists for patients with neurodegenerative diseases; as such, testing of the olfactory capability can be employed as an approach for early detection. Ariyakul et al [2011Ariyakul et al [ , 2013 proposed an OD based on miniaturized electro-osmotic (EO) pumps and a surface acoustic wave (SAW) device. Minute amounts of liquid perfume are emitted from the EO pumps, vaporized, and are then presented using fans.…”

Recently, the concept of olfaction-enhanced multimedia applications has gained traction as a step toward further enhancing user quality of experience. The next generation of rich media services will be immersive and multisensory, with olfaction playing a key role. This survey reviews current olfactory-related research from a number of perspectives. It introduces and explains relevant olfactory psychophysical terminology, knowledge of which is necessary for working with olfaction as a media component. In addition, it reviews and highlights the use of, and potential for, olfaction across a number of application domains, namely health, tourism, education, and training. A taxonomy of research and development of olfactory displays is provided in terms of display type, scent generation mechanism, application area, and strengths/weaknesses. State of the art research works involving olfaction are discussed and associated research challenges are proposed.

“…Liquid on a piezoelectric substrate is vibrated and atomized by a spurred wave generated by an interdigital transducer electrode [9]. A number of studies on SAW-based olfactory displays have been reported [7,10,11]. The other form of atomization-based olfactory display is based on micro-porous piezoelectric transducers [6].…”

Odor reproduction, a branch of machine olfaction, is a technology through which a machine represents various odors by blending several odor sources in different proportions and releases them. In this paper, an odor reproduction system is proposed. The system includes an atomization-based odor dispenser using 16 micro-porous piezoelectric transducers. The authors propose the use of an electronic nose combined with a Principal Component Analysis–Linear Discriminant Analysis (PCA–LDA) model to evaluate the effectiveness of the system. The results indicate that the model can be used to evaluate the system.
