Rise of flexible high‐temperature electronics

Flexible high‐temperature electronics is a compliant form of high‐temperature electronics to expand the application areas of conventional flexible one. In aerospace applications, electronic devices are not only required to be deformable but also to be able to withstand extreme temperatures. The disadvantages of current flexible electronics, such as high cost, large differences between components, and even requiring independent debugging, are acceptable. In recent years, flexible high‐temperature materials have been greatly developed, and flexible high‐temperature electronics have begun to emerge. In order to better understand this field, we introduce their design principles with a few recent notable achievements and then discuss the future application prospect in this perspective.
