Channel formation
First Claim
1. A system comprising:
- a first molding part; and
a second molding part configured to engage the first molding part at an interface that defines a boundary of a cavity between the first molding and second molding parts,wherein the cavity has a shape of an eye-mountable device,wherein the first molding part comprises a first surface that defines a first portion of the cavity,wherein the second molding part comprises a second surface that defines a second portion of the cavity and a protrusion that extends from a proximal end at the second surface and terminates at a distal end,wherein the protrusion is disposed within the cavity,wherein the protrusion comprises sidewalls,wherein a first distance between the sidewalls at the proximal end is greater than a second distance between the sidewalls at the distal end, andwherein the sidewalls define a portion of a conical surface with an opening angle between 10 degrees and 80 degrees.

Abstract
A body-mountable device may be formed of a polymeric material. A molding form can define a cavity and polymeric material can be formed using the mold to create a device shaped in accordance with the cavity. Electronics disposed on a substrate can be encapsulated within the polymeric material by forming a first layer of polymeric material, positioning the substrate on the first layer, and then forming a second layer of polymeric material over the substrate. A channel can expose a sensor disposed on the substrate. The channel may be formed while molding the second layer of polymeric material over the substrate. The molding form can include a protrusion that extends toward the sensor. A sacrificial sealant material can be applied to the sensor or the protrusion to create a seal between the protrusion and the sensor. The polymeric material forms around the sealed protrusion to create the channel.

3. A body-mountable device comprising:
-
a polymeric material; a substrate having a sensor disposed thereon, wherein the substrate is substantially encapsulated within the polymeric material; and wherein the sensor is exposed through a channel in the polymeric material, wherein the channel extends between the sensor and an exterior surface of the body-mountable device, wherein the channel is bounded by sidewalls, wherein the channel comprises an edge between the exterior surface and one of the sidewalls, and wherein the edge provides an angle greater than 90 degrees between the exterior surface and the sidewall. - View Dependent Claims (4, 5, 6)
