Abstract
A soft, hermetic liquid metal-based seal is developed to encapsulate electrical components in stretchable systems. The packaging material allows stretchability and prevents the permeation of reactive substances both inside and outside the liquid metal-based seal. Electrical performance of stretchable components in a water-based lithium-ion battery with and without the liquid-metal-based seal is well explicated under different conditions. The permeability is also validated in both a phase-change-based heat transfer device and a wireless communication device. Finally, we provide new insights into the remaining challenges and future directions of permeability in wearable point-of-care systems.
