Researchers developed a new metamaterial that can detect the order of external operations - EurekAlert

Researchers from Tel Aviv University and Los Alamos National Laboratory have developed a novel mechanical metamaterial that remembers the order of actions performed on it, much like a computer following a sequence of instructions. Unlike ordinary materials that respond in the same way to a sequence of external manipulations regardless of their order, the new metamaterial – named ‘Chaco’ after the archaeological site of Chaco Canyon in New Mexico – exhibits history-dependent behavior, thus opening a pathway to exciting applications in memory storage, robotics, and even mechanical computing. The research was led by Chaviva Sirote-Katz, Dor Shohat, Dr. Carl Merrigan, Prof. Yoav Lahini and Prof. Yair Shokef from Tel Aviv University, and Dr. Cristiano Nisoli from Los Alamos National Laboratory.
