“…In particular, the drive toward smaller and thinner devices to improve operating speeds and levels of integration in conventional ICs has immediate and direct benefi ts in stretchable electronics because these same geometries lead to favorable mechanical properties. Such synergies greatly enhance the prospects not only for biointegrated electronics 24 , 38 -40 , 44 , 45 and bioinspired device design, 37 , 79 -80 as described here, but also for many other classes of stretchable, curvilinear technologies in portable photovoltaics, 74 conformal thermoelectric, 87 curvilinear active antennas, 88 solid-state lighting systems, 23 , 24 energy harvesters, 41 , 89 and others. At the same time, many compelling opportunities for continued basic research follow from the unusual and extreme materials heterogeneity inherent in these systems.…”
