This prototype costs ~$20 to recreate in Gener8’s engineering lab, where most parts were readily available. The cost to recreate this prototype from scratch is ≈ $210. Competing designs can easily cost > $1000.

• Fine-tuning droplet size: Implement advanced control algorithms or design modifications to precisely adjust the droplet size within a desired range. This could involve optimizing parameters such as fluid pressure, nozzle diameter, and actuation timing.

• MATLAB imaging/photographing droplets: Integrate MATLAB or similar imaging software to accurately capture and analyze droplet size, shape, and consistency. This would provide valuable data for evaluating the performance of the droplet generator and identifying areas for improvement.

• Aluminum fluid chamber: Investigate the use of aluminum or other materials for the fluid chamber to enhance durability and acoustic conductivity, which can be crucial for droplet formation.

• Source a more powerful PZT: Research and procure a more powerful piezoelectric transducer (PZT) to increase the effectiveness of droplet ejection and achieve higher throughput rates. This may require collaborating with specialized suppliers or securing additional funding for the acquisition of advanced components.

• Smaller nozzles: Experiment with smaller diameter nozzles to produce finer droplets with increased precision and control. This could involve exploring alternative manufacturing methods or sourcing specialized nozzles from suppliers.

• Pump: Explore the use of a peristaltic pump to optimize fluid delivery to the fluid chamber. This implementation will minimize changes in Δh over time.
