With the increasing number of space debris and extreme working environment, the space station faces the risk of cabin damage. Once the leakage occurs, it must be repaired in time. Identifying the shape of leaks can guide for astronauts to make pluggi

Composite materials have been widely used in spacecraft structures. Due to the harsh environment in space, gas leakage will occur in the structure, so it is necessary to locate the leakage position in time. In this paper, a beamforming localization m

Nanofluidic channels with a depth of ∼100 nm were developed as a leak element, where the fluidic channels were etched on silicon wafer by reactive ion etching and then enclosed by direct silicon bonding. Instead of the Torr-seal gluing method, a ti
