Abstract:
"Design, Simulation and Experimental Study of Shape Memory Alloy and Micro-Motor Activated High Pressure Optical Cell for Bio-Physical Studies"
This research focuses on designing and constructing an actuator with concentric shape memory alloy (SMA) and compressive springs to facilitate the mixing and stirring of two solutions within a high-pressure optical cell. The SMA helical tensile spring is designed to pull out a stopper, while a helical compressive spring provides a biasing force and agitates the solutions. The design addresses the limitations of previous models by ensuring the lower half of the cuvette remains clear for optical observation. The paper discusses the design of the SMA actuator, testing of the springs, and the mixing process itself. The use of a conductive adhesive is highlighted as a critical component for both spring alignment and electrical conductivity. The study also includes an assessment of the nickel-titanium SMA's biocompatibility with proteins and phospholipids.
