Wearable devices include those with a variety of functions and a smaller size, such as smart watches or smart glasses, as well as devices with functions that focus on a specific application type and need to cooperate with other devices such as smartphones (this includes smart bracelets for smart jewelry that monitors health conditions).

As technology progresses and user needs change, so too, are wearable device appearances and functions. Batteries for wearable devices require a small size and a high power density. We offer batteries that meet those requirements, to the praise of customers across the world.
