Summary

Making stretchable thin-film electronics presents considerable scientific and technological challenges: (i) Can substrates that are inherently extensible support reliable fabrication of thin-film conductor and semiconductor devices? (ii) Can device materials withstand mechanical deformations without compromising their electrical properties? and (iii) Which applications will be enabled with such ultracompliant electronic skins? This chapter illustrates those challenges and potential routes to overcome them. Section 4.2 reviews the physical properties of silicone rubber – the substrate hosting the thin-film devices. Section 4.3 describes the mechanical design to implement and use robust stretchable thin-film circuits. Section 4.4 reviews materials and characteristics of stretchable metallization. Section 4.5 highlights examples of stretchable thin-film devices.
