a Schematic illustration of the production flow combining the detachable interface design and lift-off technology for densely integrated stretchable CNTs electrodes. b High-resolution optical microscope images of the micropatterned stretchable electrodes with feature size of 2 μm on Si-wafer (upper) and stretchable devices (bottom). c Optical microscope image showing the integrated intrinsically stretchable organic transistor matrix with a high density of 41,000/cm2. d Photographic images of the fabricated stretchable CNT electrodes with different patterns. e Conductivity of the CNT electrodes transferred onto the stretchable substrate with and without the assistance of LiF layer constructed for the detachable interface. f The measured peeling force as a function of applied displacement in the transfer process of prefabricated CNT electrodes with pristine interface and detachable interface. g Mechanical simulation showing the Von Mises strain distribution during the peeling process of prefabricated CNT electrodes with pristine interface and detachable interface.
