SMA project flower petal

This flower petal was made by using the curling mechanism (sewing flexinol wire to paper). It was made with 0.006 HT flexinol, which requires about 0.400A of current to run properly. This video shows the drop in resistance of the wire as it heats up, which results in the shape change becoming faster as the wire heats up and more current is able to run through the wire. • Made by Jessie Thompson as part of the MIT/RISD paper-based electronics workshop. • http://web.media.mit.edu/~jieqi/
