Engineers Create Artificial Skin That "Feels" Temperature Changes

Chiara Daraio, Professor of Mechanical Engineering and Applied Physics, and colleagues have developed an artificial skin capable of detecting temperature changes using a mechanism similar to the one used by the organ that allows pit vipers to sense their prey. [Caltech story]

The Utility of Instability

08-08-16

Professors Dennis M. Kochmann and Chiara Daraio along with colleagues from Harvard have designed and created mechanical chains made of soft matter that can transmit signals across long distances. Because they are flexible, the circuits could be used in machines such as soft robots or lightweight aircraft constructed from pliable, nonmetallic materials. "Engineers tend to shy away from instability. "Though there are many applications, the fundamental principles that we explore are most exciting to me," Kochmann says. "These nonlinear systems show very similar behavior to materials at the atomic scale but these are difficult to access experimentally or computationally. Now we have built a simple macroscale analogue that mimics how they behave." [Caltech story]

Winners of the 2012 Demetriades - Tsafka - Kokkalis Prizes Announced

06-14-12

The student winners of the 2012 Demetriades - Tsafka - Kokkalis Prizes were announced at a special luncheon with the Demetriades - Tsafka – Kokkalis family. Philip Romero received the prize in Biotechnology for his work on developing statistical models of proteins with Frances Arnold. Michael Mello was the recipient of the prize in Seismo-Engineering, Prediction, and Protection for his work with Ares Rosakis on developing a novel methodology for identifying the unique ground motion signatures of supershear earthquakes. Leslie O’Leary received the prize in Environmentally Benign Renewable Energy Sources for her pathbreaking work on the properties of semiconductor interfaces with Nate Lewis and Bob Grubbs. This year there were two winners for the prize in Nanotechnology. One winner was Andrew Jennings for his experimental and modeling work in nanomechanics with Julia Greer. The other winner of the Nanotechnology prize was Jordan Raney who has worked with Chiara Daraio to develop new chemical synthesis methods to control the properties of carbon nanotubes.
