Fig. 1: Stretchable inorganic transistors with high integration density.

a Combination of rigid functional islands and stretchable interconnects to build stretchable electronic system. b Devices are arrayed in serpentine strings, where only passive wirings were placed before. c Integration density rises when the devices also lie on the serpentine bridges in addition to rigid island (Supplementary Fig. 2 for the details in calculation). d Current bulky stretchable electronics can be miniaturized by the proposed approach.
