An electroactive polymer (EAP) syringe pump for microfluidic injections.
A more cost effective, mechanically simpler and more intuitive system for surgeons.
In cell therapy operations, microscopic volumes of low viscosity fluids are delivered to the brain through extremely thin and long steel needles.
Very precise syringe pumps that control the flow rates and injection volumes of these fluids are required.
Existing microfluidic syringe pumps have a non-disposable infrastructure, rely on motor-driven mechanisms, require heavy carts for transport, and are very mechanically complex.
Electroactive Polymers (EAPs) are thin films that provide dynamic movement upon electrical stimulation.
As a material-driven design project, I explored several concept mechanisms to integrate EAPs into these systems, to improve the user experience for surgeons.
Visualizing concept directions for using EAPs as mechanical actuation.
Proof-of-concept model to gain surgeon feedback, test handheld ergonomics, and establish touch points.
Electrical current runs through the EAP, it flexes against the housing, and squeezes an inner flexible tube which holds a disposable saline sac. This sac is ruptured by a double-ended needle to dispense cell fluid accurately and precisely.
