Physicists build muscle for shape-changing, cell-sized robots

Media Note: Images can be viewed and downloaded at https://cornell.box.com/v/RobotExoskeleton. You can also watch this Vimeo video about the work. ITHACA, N.Y. – An electricity-conducting, environment-sensing, shape-changing machine the size of a human cell? Is that even possible? Cornell physicists Paul McEuen and Itai Cohen not only say yes, but they’ve actually built the “muscle” for one. With postdoctoral […]

Top-flight rheometer allows for outside-the-box research

ITHACA, N.Y. – Until earlier this month, if students in Itai Cohen’s research group wanted to perform advanced measurements on a fluid – such as applying both rotation and sinusoidal oscillations to gauge whether the flow disruption was hydrodynamically or contact-mediated – they’d have to drive 330 miles east. Now, thanks to a loan from […]

Shape-shifting octopus inspires 3-D morphing material

Media Note: Videos of the morphing materials can be viewed and downloaded at https://cornell.box.com/v/3dtexture. An interview and demonstration of engineering professor Rob Shepherd explaining the new work can also be viewed on YouTube. ITHACA, N.Y. – A Cornell University engineering and physics team is using the octopus as inspiration for a method to morph flat […]
