Electronic skin: architecture and components
Wagner, Lacour, Jones, Hsu, Sturm, Li, Suo, Physica E 25 (2004), 326-334
Flexible electronics have a host of potential applications ranging from medicine (e.g. prosthetic skin) to flexible electronic devices. The materials traditionally used for the fabrication of circuits, such as silicon, are stiff. Flexible counterparts may be possible with the combination of a flexible substrate on which conducting metal connections can be deposited; the substrate may then sustain considerable stress. The question the authors address is how subjecting a flexible substrate to strain affects the electrical properties of the deposited conductors.
The authors initial approach to fabricating these systems was based on the creation of wavy metal films which could be reversibly stretched.
