Cold hibernated elastic memory (CHEM) is an innovative, smart material technology that uses shape memory polymers in open cellular structures. This book extensively describes CHEM self-deployable structures, provides basic property data and characteristics, discusses advantages, and identifies numerous space, commercial, and medical applications. Some of these applications have been experimentally and analytically investigated with inspiring results and are revealed here.
CHEM technology has a potential to provide groundbreaking self-deployable space structures. Some cutting-edge space CHEM concepts described in this book represent the introduction of a new generation of space deployable structures.
CHEM materials have unique characteristics that enable the manufacture of self-deployable stents and other medical devices not possible currently. One of the medical applications, the CHEM endovascular treatment of aneurysm, is being experimentally explored with promising results that would save lives.
This book provides a long list of interesting potential commercial CHEM applications that could simplify and make life easier at low cost. One of these products, the self-reconfiguring armchair, is already being set up for mass production.
This book will be of interest to all engineering researchers, scientists, engineers, students, designers, and technologists across their relevant fields of interest. The exceptional characteristics of CHEM technology are presently enabling technologists to develop many applications ranging from outer space to inside the human body. As a result, CHEM structures are in the process of reshaping our thinking, approaches, and design methods in many ways that conventional materials and approaches do not allow.
