Part 5/11:
A significant breakthrough in his research involves the activation temperatures of SMA wires. Previously, most observed applications involved hot water activation, necessitating high temperatures. Now, Paul learns that certain manufacturing processes allow SMA wires to activate at significantly lower temperatures—up to 150°C. This revelation opens new possibilities: perhaps activating the wire at room temperature or with minimal heat could lead to more practical, less energy-intensive designs. This shift challenges his assumptions about the necessity of hot water and suggests innovative avenues like cold water activation or even ambient-temperature triggers, potentially involving pumps or other energy inputs.
