Shmuel is a PhD student in the Faculty of Mechanical Engineering, at the Technion. His research focuses on designing new materials, also called metamaterials (“materials” made from carefully designed repeating micro-scale building blocks). The objective of the research is to understand the dynamic response of a chain composed of masses and bistable springs, springs which have two stable states (like switches), to impacts and vibrations. Careful design of the building blocks may enable the realization of a new class of energy-absorbing materials that cannot be found in nature, i.e. mechanical insulators that protect from vibrations and impacts. This work has the potential to revolutionize the field of energy-absorption, by the development of new metamaterials to be used in a range of applications, such as passenger protection, medical devices, and protective packaging of fragile components.
