A 3D twist on stretchable electronics
By stacking, and electrically connecting, layers of stretchable circuits, three-dimensional integrated devices can be built that are capable of wirelessly monitoring a person’s vital signs and creating human–machine interfaces. The cover shows an optical microscopy image of a four-layer stretchable device that is equipped with Bluetooth data communication capabilities and can simultaneously sense electrophysiological signals, strain, temperature, acceleration, and orientation.
