Claim:
1. A method comprising: forming a first polymer layer; positioning a structure on the first polymer layer, wherein the structure comprises a sensor; forming, in a molding piece, a body-mountable device by forming a second polymer layer over the structure positioned on the first polymer layer, wherein the first polymer layer defines a first side of the body-mountable device and the second polymer layer defines a second side of the body-mountable device opposite the first side, and wherein the molding piece comprises a surface that supports the second polymer layer as the second polymer layer is being formed and a protrusion that extends from the surface to the sensor through the second polymer layer as the second polymer layer is being formed; and removing the body-mountable device from the molding piece, wherein the body-mountable device removed from the molding piece has a channel to the sensor formed by the protrusion.
