Sigurd Wagner is developing technology for flexible large-area electronics, with emphasis on transistor backplanes made with thin-film silicon transistors, and their integration into systems. His present research is focused on (i) flexible backplanes using amorphous, nanocrystalline, and microcrystalline silicon on plastic and steel foils; (ii) the interdependence of electrical and mechanical properties in film-on-foil electronics when rolled, conformally shaped, or stretched; (iii) elastic electronic surfaces and structures; (iv) elastically stretchable metal films, (v) functional cells for large area electronics including displays, solar cells, mechatronic materials, sensor skin, and e-textiles.
