PhD Research Works

Project 01:Mechanics of Controlled Angle SAW Jetting for Droplet Deposition

  • Developed an angle-controlled SAW (LiNbO₃) jetting platform to precisely eject droplets and deposit them on a target substrate.

  • Quantified jetting/deposition behavior using high-speed imaging, oscilloscope/amplifier diagnostics, and image-based motion tracking (ImageJ).

  • Built predictive/validated relationships between actuation conditions and deposition outcomes to enable repeatable directional printing.

Project 02: Size-Selective Sorting of Microbeads via Angle-Controlled SAW Jetting

  • Designed a jetting-based sorting concept where controlled ejection direction and flight dynamics enable size-dependent bead separation.

  • Performed feasibility experiments and analysis to identify regimes for clean sorting vs. mixed trajectories.

  • Established a roadmap toward automated, high-throughput bead handling for microfluidics and sample-prep workflows.

Project 03: Predictive Angle-Controlled Jetting for Conductive Printing in Flexible Electronics

  • Developed printing workflows for carbon/graphite nanoink deposition on flexible substrates to form conductive traces.

  • Optimized jetting parameters and substrate conditions for stable deposition and improved line quality/continuity.

  • Targeted functional demonstrations (e.g., measurable conductivity / circuit-level proof of concept) for flexible electronics applications.

Project 04: Sensor Applications Enabled by Acoustofluidic Jetting

  • Investigated how controlled droplet placement and repeatable deposition can be used to fabricate or functionalize sensor surfaces.

  • Integrated rapid prototyping (CAD + 3D printing) with jetting experiments to iterate device layouts and test protocols.

  • Developed an application pipeline connecting controlled deposition → device fabrication steps → sensing validation.

Project 05: Acoustofluidic Jetting–Based Platelet Separation from Whole Blood/ Plasma

  • Developed an acoustofluidic jetting concept for blood component processing, targeting platelet separation to support plasma preparation.

  • Defined experimental workflows and safety-minded handling steps for blood sample testing and evaluation.

  • Positioned the method toward faster sample preparation for downstream diagnostics and biosensing.
