Executive Summary
Researchers at Empa Thun have developed a method to deploy artificially produced aluminum oxide interlayers (5 nanometers) in multilayered materials. This makes satellite insulation more stretchable, more crack-resistant, and opens applications in flexible electronics, medical sensors, and foldable devices. The findings could sustainably transform materials science and aerospace engineering.
