Aerosol jet printing process for surface acoustic wave (SAW) microfluidic devices. a Schematic of the fabrication process and mechanism of the aerosol jet-printed SAW microfluidic devices. Interdigital transducers are fabricated via aerosol jet printing and actuated to create SAW that propagates into the droplet to allow for acoustic forces, including acoustic radiation and acoustic streaming, to act on the droplet and the particles inside the droplet. b Image of an aerosol jet printer with a printed PEDOT:PSS SAW microfluidic device. c Image of a silver nanowire-based interdigital transducer on a lithium niobate substrate. d Timeline and number of fabrication steps comparison between the cleanroom and aerosol jet printing fabrication methods for SAW microfluidic devices.
