1. System description

Shape memory alloy (SMA) has excellent characteristics of noiseless driving, high power to weight ratio, integrated driving and so on. Combined with the structural transformation of materials in the driving process, the relationship between stress-strain, temperature resistance, strain resistance and martensitic transformation in the thermal driving process of wire driven simulated finger is analyzed by the SMA-1 dynamic characteristics measurement system.

     2. Parameters

        1) Temperature controller:-40~150℃, accuracy: ±0.2℃.

        2) Stress measurement accuracy ± 0.1g, displacement measurement accuracy ± 1um..

        3) Data acquisition unit range and accuracy : 1×10^-7～1×10^2 Ω,1uΩ.

        4) Standard samples: 1Ω、10Ω、100Ω, accuracy 0.05%,3ppm.

        5) Synchronously measure the stress and strain, phase change resistance, phase change temperature, fatigue and other wire properties.
