Abstract:
An eye-mountable contact lens (110, 210a) is provided that includes electronics (150, 160, 170) encapsulated within a rigid, gas-permeable polymeric material (120, 330b). The rigid, gas-permeable polymeric material (120, 330b) can be mountable to a corneal surface of an eye (fig 1C) or can be disposed on or within (fig 2A) a flexible polymeric material (220a) that is mountable to the corneal surface of the eye. The rigid, gas-permeable polymeric material (120, 330b) can provide structural rigidity and protection to the electronics (150, 160, 170) and/or can allow for long-term dry storage of a chemical sensor of the electronics (150, 160, 170). The rigid, gas-permeable polymeric materials (120, 330b) of the provided eye-mountable devices (110, 210a) can be formed by curing a precursor material (330a) on or around the electronics and subsequently removing portions of the polymeric material formed by the curing, e.g., to form a rigid, gas-permeable contact lens (110, 210a) that at least partially encapsulates the electronics (150, 160, 170) and that has a curved shape that is able to be mounted to a corneal surface of an eye (fig 1C).
Abstract:
A multi-colored display includes a semiconductor substrate layer, a first light emitting diode ("LED") integrated onto the semiconductor substrate layer to natively emit pump light having a first color, a second LED integrated onto the semiconductor substrate layer to natively emit the pump light having the first color, and a first wavelength conversion layer disposed over an emission aperture of the second LED to convert the pump light natively emitted from the second LED to first output light having a second color different from the first color of the pump light. The first wavelength conversion layer includes a first matrix of quantum dots. The first and second LEDs are integrated into a single semiconductor die.
Abstract:
The present disclosure relates to a rigid sensor stopper adapted for use in a drug delivery device. In one implementation, a rigid sensor stopper may include a transducer, a power source, a rigid molding or casing, and at least one elastomeric seal. The molding may be formed from overmolding or insert molding, and the casing may be formed from injection molding, machining, or forged casing. The at least one elastomeric seal may include at least two o-rings.
Abstract:
A flexible electronic device is provided that includes electronics, metal traces, and other components at least partially encapsulated in a protective, corrosion- and fluid-resistant encapsulating adhesive coating. The device include electronics, sensors, and other components disposed on a flexible substrate that is configured to be mounted to a body or disposed in some other environment of interest. The encapsulating adhesive coating is flexible and adheres securely to the electronics, metal traces, and other components disposed on the flexible substrate. The encapsulating adhesive coating prevents voids from forming proximate the components within which water or other chemicals could be deposited from the environment of the device. The encapsulating adhesive coating could include silicone or other flexible highly adhesive substances. The encapsulating adhesive coating could be a conformal coating.
Abstract:
Systems and methods for the wireless transfer of power between two hermetically sealed devices are described herein. An example system may include a battery package and a hermetically sealed body-implantable electronic device having an electronics package. The battery package may include one or more alignment structures, configured to removably align the battery package with the electronic device, a battery, and a wireless power transceiver. At least the battery and the wireless power transceiver of the battery package may be contained within a hermetic material separate from the electronic device. Power may be wirelessly transferred between the devices by any means, including inductive coupling or capacitive coupling. In some examples, the hermetically-sealed devices may be implanted in a living body.
Abstract:
An example device includes a lithium-based battery 100 having conductive battery contacts 206, 208 protruding from a surface 202 of the battery, where a non-conductive potion 210 of the surface of the battery separates the conductive battery contacts. The battery is a type that undergoes an expansion during charging in which the expansion of the lithium-based battery includes an outward bulging of the non-conductive portion of the battery surface. The device includes a substrate 200 having conductive substrate contacts 214, 216. The conductive battery contacts are electrically connected to the respective conductive substrate contact via a flexible electrically-conductive adhesive 600, 602 that physically separates the conductive battery contacts from the respective conductive substrate contacts and allows for relative movement therebetween caused by the expansion of the lithium-based battery.
Abstract:
An eye-mountable de vice includes a transparent polymer and a structure embedded in the transparent polymer. The transparent polymer defines a posterior side and an anterior side of the eye-mountable device, and the transparent polymer has a concave surface and a convex surface. The structure includes a substrate, an antenna comprising a conductive loop, and a sensor that is configured to detect an analyte. The substrate includes a loop portion and a tab portion, where the loop portion has an outer circumference defined by an outer diameter and an inner circumference defined by an inner diameter, and where the tab portion extends from the inner circumference of the loop portion towards a center of the loop portion. The conductive loop is disposed on the loop portion of the substrate between the inner circumference and outer circumference, and the sensor is disposed on the tab portion of the substrate.
