I used Shape Memory Alloy (SMA) wires to make a sample of tissue showing smocking point. Smocking is an old textile technique that gathers fabric in certain pattern to create 3D decorative pattern on textiles. | I used Shape Memory Alloy (SMA) wires to make a sample of tissue showing smocking point.

I used conductive thread to connect the 4 muscle wires to create a smocking pattern. |
I then connected the extremities of the circuit to 1, 2 and then 3 x 4,5 V batteries. The circuit didn't behave as expected and only 1 wire at the time was going back to its original shape (a coil shape). | I then connected the extremities of the circuit to 1, 2 and then 3 x 4,5 V batteries.
