Abstract: The disclosed technology provides for a device and method related to powering an electronic stylus with a removable, integrated battery that acts as a structural segment and external casing along the long axis of the stylus body. The integrated battery incorporates interlocking features, which removes the need for an external tube around a battery cell. As a result, the electronic stylus has one structural component performing multiple functions (e.g., providing power, functioning as the stylus casing), which achieves a more lightweight and compact electronic stylus. The placement of the battery along the long axis can vary to provide comfortable weight distribution for writing, which can involve an interlocking interface at one end of the battery or at both ends of the battery (e.g., to interlock with one or both ends of the electronic stylus). The disclosed technology provides for a device and method related to powering an electronic stylus with a removable, integrated battery that acts as a structural segment and external casing along the long axis of the stylus body. The integrated battery incorporates interlocking ...more ...less
