Abstract
Designs, strategies and methods for forming tube shaped batteries are described. In some examples, hermetic seals may be used to seal battery chemistry within the tube-shaped batteries. This may improve biocompatibility of energization elements. In some examples, the tube form biocompatible energization elements may be used in a biomedical device. In some further examples, the tube form biocompatible energization elements may be used in a contact lens.
