[摘要] An important trend in electronicsinvolves the development of materials, mechanical designs and manufacturingstrategies that enable the use of unconventional substrates, such as polymerfilms, metal foils, paper sheets or rubber slabs. The last possibility is particularlychallenging because the systems must accommodate not only bending but alsostretching. Although several approachesare available for the electronics, a persistent difficulty is in power suppliesthat have similar mechanical properties, to allow their co-integration with theelectronics. Here we introduce a set ofmaterials and design concepts for a rechargeable lithium ion battery technologythat exploits thin, low modulus silicone elastomers as substrates, with asegmented design in the active materials, and unusual ‘fractal’ interconnectstructures between them. The resultenables reversible levels of stretchability up to 300%.
