Closed-Loop Axisymmetric Drop Shape Analysis for Droplet Manipulation

Case ID: 01106

Description

Inventors at the University of Hawaii have developed a novel method for closed-loop axisymmetric drop shape analysis (CL-ADSA), taking it beyond traditional surface tension measurement to a sophisticated tool for manipulating millimeter-sized droplets. This closed-loop system enables real-time measurement AND precise control of droplet properties such as volume, surface area and surface tension. The feedback control system continuously calculates changes in droplet parameters and automatically drives corrective action to maintain desired droplet characteristics. Inventors have demonstrated the accuracy, versatility, applicability and automation of this new CL-ADSA technique, proving effectiveness in automating droplet manipulation in a variety of material and surface science applications.

 

Applications

  • Synthesis of thin-film materials
  • Control of interfacial reactions
  • Operation of digital microfluidics
  • Biophysical simulations

 

Advantages

  • Faster and more accurate than currently available ADSA methods.
  • Real-time analysis eliminates the need for prior image acquisition.
  • Feedback control allows for an entirely automatic system, thereby eliminating the need for any human intervention.
  • Applicable to nonlinear (e.g. millimeter-sized droplets, bubble, or other) drop shapes.
  • Precise control and manipulation of droplet properties (volume, surface area, and surface tension).
