1. A stretchable integrated circuit (IC) system comprising:

  • a flexible substrate;

    a first device island mounted to the flexible substrate and comprising a first integrated circuit (IC) device fabricated from a rigid semiconductor material;

    a second device island mounted to the flexible substrate and comprising a second integrated circuit (IC) device fabricated from a rigid semiconductor material;

    a third device island mounted to the flexible substrate and comprising a third integrated circuit (IC) device fabricated from a rigid semiconductor material;

    a first flexible electrical interconnect electrically connecting the first IC device to the second IC device, such that a distance between the first IC device and the second IC device can be changed in a first dimension while maintaining an electrical connection between the first IC device and the second IC device; and

    a second flexible electrical interconnect electrically connecting the second IC device to the third IC device, such that a distance between the second IC device and the third IC device can be changed in a second dimension while maintaining an electrical connection between the second IC device and third IC device.
