摘要：
A method of sensing an ambient heat transfer condition surrounding a shape memory alloy element includes heating the shape memory alloy element, sensing the resistance of the shape memory alloy element, and measuring the period of time taken to heat the shape memory alloy element to a pre-determined level of a resistance characteristic. The ambient heat transfer condition surrounding the shape memory alloy element is calculated by referencing a relationship between the period of time taken to heat the shape memory alloy to the pre-determined level of the resistance characteristic and the ambient heat transfer condition.
