A stretchable array of commercially available inorganic light‐emitting diodes (LEDs) shows no change in electrical properties under repeated tensile strains in excess of 100%. The array is built using a widely applicable fabrication process in which the LEDs can be substituted for other commercially available electronic components to build all types of stretchable electronic systems, thereby expanding the application space of electronics.

A light‐emitting‐diode array wrapped around the human thumb illuminates how electronics in the future will be stretchable and conformable rather than rigid and brittle. In the article , Kevin Dowling, William J. Arora, and co‐workers show how to integrate commercially available inorganic electronics with low‐modulus rubber substrates to make electronics of the future more compatible with the human body and the world that we live in.
