BATTERIES OF TUBULAR BIOMEDICAL DEVICES WITH CHEMICALLY DEPOSITED SEAL Russian patent published in 2018 - IPC H01M10/04 H01M10/6235 H01M2/02 H01M2/08 A61F9/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely, to biocompatible tubular-shaped batteries and a method of manufacturing them, in particular by forming tubular molds from solid structures. In some examples, the field of use of biocompatible batteries may include any biocompatible device or article for which power is required, for example, implantable pacemakers, electronic tablets for monitoring and/or testing biological function, surgical devices with active components, contact lenses. Some medical devices may include electrical components such as semiconductor devices that perform a variety of functions and can be embedded in a variety of biocompatible and/or implantable devices. Biocompatible battery includes a tubular structure with an interior space forming the cavity. First encapsulating layer encapsulates at least an electrically active component and a biocompatible battery. In some examples, the first encapsulating layer is used to form a contact lens skirt surrounding the internal components of the electroactive lens with a biocompatible hydrogel layer that interacts with the user's eye surface. For sealing, a sealing material is used in the form of a galvanic outer metal coating deposited by a chemical deposition method, an epoxy adhesive, as well as a metal film deposited by the physical vapor deposition method (PVD).

EFFECT: technical result of the invention – increase in the safety, reliability, and compactness of the power supplies of semiconductor components within the biocompatible device by improving the integrity of the tubular biocompatible battery.
