SMA mechanism: double curling
Channel: Jie Qi
Date: 2012-02-01

This mechanism uses two curling pieces moving opposite each other to create a claw-like motion.  The curling strip is made by sewing flexinol wire to the paper strip and then attaching the center of the strip to the base piece of paper.  When the wire heats up (from current running through), it contracts causing the paper to curl.

Made by Shaun Salzberg as part of the MIT/RISD paper-based electronics workshop.
