US 12,671,193 B2 · Systems and methods for ingress sealing of electrical contacts for wearable or implantable devices

Abstract

Systems and methods for ingress sealing of electrical contacts for wearable or implantable devices are provided herein. An example device may include a housing portion defining a depression having one or more openings. The device may also include one or more electrical contacts configured to provide an electrical pathway between an external surface and an interior surface of the housing portion. The device may include an insulator disposed within the depression, the insulator including one or more apertures configured to receive the electrical contacts. The insulator may electrically isolate the electrical contacts from the housing portion and from each other. The electrical contacts may be each positioned within a respective aperture of the insulator and extend through a respective opening of the openings. The device may include an anisotropic conductive film (ACF) positioned over the electrical contacts to seal the apertures and the openings to prevent ingress of contaminants.

Dependent claims

A device comprising:

a first housing portion defining a depression having one or more openings providing access from an external environment to an interior of the first housing portion;
an insulator disposed within the depression and comprising one or more apertures, each aperture corresponding to a different one of the one or more openings;
one or more electrical contacts positioned to provide an electrical pathway between an external surface of the first housing portion and an interior surface of the first housing portion via a respective one of the one or more openings, wherein the insulator electrically isolates the one or more electrical contacts from the first housing portion and from each other and wherein the one or more electrical contacts are each positioned within a respective aperture of the insulator and extending through the corresponding opening of the one or more openings;
and
an anisotropic conductive film (ACF), wherein the ACF is positioned over the one or more electrical contacts to seal the one or more apertures and the one or more openings to prevent ingress of contaminants.

A method of sealing a wearable device, the method comprising:

providing a first housing portion defining a depression having one or more openings providing access from an external environment to an interior of the first housing portion;
disposing an insulator having one or more apertures formed therein into the depression of the first housing portion, wherein the depression is configured to receive the insulator, each aperture corresponding to a different one of the one or more openings;
disposing one or more electrical contacts into the one or more apertures of the insulator, wherein the one or more apertures are configured to receive the one or more electrical contacts such that at least a portion of each of the one or more electrical contacts is exposed to an external environment via the corresponding one of the one or more openings of the depression, and wherein the insulator electrically isolates the one or more electrical contacts from the first housing portion and from each other;
disposing an anisotropic conductive film (ACF) onto the first housing portion, wherein the ACF is configured to be electrically conductive along a thickness of the ACF;
generating a seal using the ACF;
and
disposing an electrical circuitry to align with and be in contact with at least a portion of each of the electrical contacts,
wherein the seal formed by the ACF is between the first housing portion and the electrical circuitry.
