Design Principles

"Implement closed-loop feedback mechanisms using integrated sensors to enhance the robustness and precision of automated manufacturing processes."

This approach moves beyond simple volumetric dispensing by providing feedback on the extrusion process itself. Designers can leverage this to create more robust and reliable fluid handling systems, reducing failures and improving the quality of manufactured outputs, particularly in additive manufacturing or automated laboratory settings.

What This Means for Your Design

Adding a sensor that measures the pushing force in a syringe pump helps it detect blockages and dispense liquids more accurately.
