Stretchable Battery Packaging Could Power the Future of Wearable Devices

Wearable devices have garnered attention for their potential as sensors that could monitor various biomarkers, a means of drug delivery, medical devices, and more. In order for these wearable devices to be functional and practical, they need to have batteries that are stretchable and highly deformable. While there has been research on how to improve battery flexibility while maintaining battery life and other desirable properties, less attention has been paid to the importance of how to protect batteries from moisture and gases. Because wearable devices are exposed to the atmosphere, it is important to extend battery life while protecting the batteries from atmospheric moisture and gases.
