摘要： A method and device for electro-thermo-mechanical tensile testing of wires is disclosed. The device includes a sample frame having upper and lower parts, with the upper part coupled to the lower part through a plurality of sacrificial supports, the upper and lower parts each having an electrical contact pad. The upper and lower parts are electrically non-conductive. The device also includes a wire sample with tracking beads, the wire sample affixed to the upper and lower parts such that the electrical contact pads of the upper and lower parts are communicatively coupled through the wire sample. The device also includes a piezo actuator coupled to the upper part, a weight coupled to the lower part, a power supply configured to pass a current through the wire sample, an electronic balance beneath the weight, and a digital camera pointed at the tracking beads of the wire sample.
