I was reminded of this today upon seeing Ghalya’s smart flower.
Dr. Lining Yao is right here on campus, where she runs the Morphing Matter Lab. In the video below from Google Design (9 minutes in) she demonstrates a flower printed to self fold into a flower. And then later she shows materials that morph when exposed to moisture (16 minutes in), and even later a soft robotic bunny that has tendons that actuate to hug you (29 minutes in). I recommend watching the whole video!
