There’s Zotac’s VR GO 4.0 wearable backpack PC, and then an innovative new stretchable battery packaging that could be used in future wearable devices, like sensors that could monitor various biomarkers as well as for drug delivery. To make this possible, the team coated a thin layer of liquid metal onto a gold-deposited thermoplastic polyurethane film using the layer-by-layer method to create a flexible film with a high gas barrier.
Since wearable devices are typically exposed to the elements, it’s vital to extend battery life while protecting the batteries from atmospheric moisture and gases. After testing this flexible film with a high gas barrier, they discovered that it has superb oxygen gas impermeability under mechanical strain and extremely low moisture permeability. This means that it’s capable of operating reliably in air due to the stretchable gas barrier film that they developed.

“It is exciting that in addition to the development of a stretchable battery, which could be used in the next generation of smart devices, including future wearable devices, films with high gas and moisture barrier properties can be achieved by using a novel material called liquid metal. This research contributes to the social implementation of stretchable devices,” said Hiroki Ota, corresponding author of Yokohama National University’s Department of Mechanical Engineering.
