Abstract
Smart glasses integrate a number of energy-consuming elements. Providing battery cells to power these components while also enabling adequate battery life can result in designs that are heavy and uncomfortable. An important factor related to comfort is the weight distribution and center of gravity of the device. This disclosure describes techniques to tune the center of gravity of smart glasses by adjusting the distribution of battery cells across the structure of the glasses. Battery cells are arranged in a stacked configuration, with each cell sized and shaped according to the space available at its location. The distribution of battery-stack layers can vary over the length of the glasses to achieve even weight distribution. A greater volume of battery cells can be integrated while maintaining user comfort by achieving uniform weight distribution. The center of gravity can be tuned for optimum comfort by leaving gaps between battery sections. For flexibility in system integration, such gaps can be filled with other components such as speakers, sensors, chipsets, etc.
