New electronic components and materials for extreme environments like Hypersonic flight , Planetary exploration and Military Systems

March 8, 2018 Electronics & EW, Material Comments Off on New electronic components and materials for extreme environments like Hypersonic flight , Planetary exploration and Military Systems

“Electronics have dramatically changed the way we live, conduct business, communicate, and educate. Visions of the future foretell of ubiquitous computing and sensing. However, the environments in which electronics can reliably operate are limited. In consumer applications, typical operating temperatures range from -40° to 85°C. The “wider” military temperature range …
