Abstract The development of stretchable electronics will thrive on the novel interface structure to solve the stretchability-conductivity dilemma, which is still a great challenge. Herein, we report a nano-liquid metal (LM)-based high-robust stretchable electrode (NHSE) with a self-adaptable interface that mimics water-to-net interaction. Based on in situ assembly of electrospun elastic nanofibers scaffold and electrosprayed LM nanoparticles, the NHSE exhibits an extremely low sheet resistance of 52 mΩ/□. It is not only insensitive to a large degree of mechanical stretching (i.e., 350% electrical resistance change upon 570% elongation), but also immune to cyclic deformation (i.e., 5% electrical resistance increase after 100,000 stretching cycles with 100% elongation). These key properties are far more superior to the state-of-the-art reports. Its robustness and stability are verified under diverse circumstances, including long-term exposure in air (420 days), cyclic washing (30,000 times), and resilience against mechanical damages. The combination of conductivity, stretchability and durability makes the NHSE a promising conductor/electrode solution to flexible/stretchable electronics for applications such as wearable on-body physiological signal detection.

Conductive traces of elastomer embedded with liquid metal droplets exhibit little change in electrical resistance when stretched to large strains. Computational modeling is performed to better understand this remarkable piezoresistive property.
