On the hardware front, activation of VMAs using with Gaussian or Lorentzian pulses have been demonstrated to result in a more uniform distribution of droplet sizes, albeit at the expense of atomization rate. Producing these bespoke waveforms could facilitate experiments with greater dependence on droplets of a specific diameter. Built-in automatic frequency tuning is another potential extension, allowing plugand-play operation with a range of VMA form factors and solvents with widely varying physical properties.
