    Abstract: A body-mountable device can include a transparent material and a substrate at least partially embedded in the transparent material. The transparent material can have a mounting surface and a surface opposite the mounting surface. A light source can be disposed on the substrate and configured to emit light through the surface opposite the mounting surface. The light source can be controlled by circuitry disposed on the substrate. The circuitry can be configured to receive modulation instructions and modulate the light emitted by the light source based on the modulation instructions.

    Abstract: A reader for communicating with both an eye-mountable device and a display device is provided. The reader can transmit radio frequency power to a tag that is part of the eye-mountable device. The reader can communicates with the tag using a first protocol. Communicating with the tag can include having the reader request data from the tag and receive the requested data from the tag. The reader can process the received data. The reader can store the processed data. The reader can communicates with the display device using a second protocol, where the first and second protocols can differ. Communicating with the display device can include having the reader transmit the stored data to the display device. The display device can receive the transmitted data, process the transmitted data, and generate one or more displays including the transmitted and/or processed data.

    Abstract: An eye-mountable device includes an electrochemical sensor embedded in a polymeric material configured for mounting to a surface of an eye. The electrochemical sensor applies a stabilization voltage between a working electrode and a reference electrode to allow the amperometric current to stabilize before powering measurement electronics configured to measure the amperometric current and communicate the measured amperometric current. The electrochemical sensor consumes less power while applying the stabilization voltage than during the measurement. The measurement is initiated in response to receiving a measurement signal at an antenna in the eye-mountable device.

    Abstract: Apparatus, systems and methods employing contact lens sensors are provided. In some aspects, a contact lens includes a substrate and a circuit. The circuit can include: one or more sensors disposed on or within the substrate, that sense a feature associated with a wearer of the contact lens; and a compensation circuit disposed on or within the substrate, coupled to the sensor(s) and that outputs information to adjust an output of the sensor(s). The compensation circuit can include: a temperature component that senses the temperature of the sensor(s); and a communication component that outputs information indicative of the temperature of the sensor(s), and receives information associated with adjusting the output of the sensor(s). In other aspects, a contact lens includes a circuit that senses the body temperature, or ambient temperature outside of the body, of the contact lens wearer. Sensor fusion and/or calibration can be performed based on the information.

    Abstract: An eye-mountable device can include a transparent material and a substrate at least partially embedded in the transparent material. The transparent material can have a concave surface and a convex surface, with the concave surface configured to removably mount the eye-mountable device on a corneal surface overlaying a pupil. A light source can be disposed on the substrate and configured to emit light through the concave surface and towards the corneal surface such that the emitted light is viewable through the pupil. The light source can be controlled by circuitry disposed on the substrate. The circuitry can be configured to modulate the light emitted by the light source to provide modulated light.

    Abstract: A body-mountable light sensing device includes a photodiode configured to receive light from a portion of subsurface vasculature and electronics configured to operate the photodiode to measure the received light. The electronics include a photodiode voltage source configured to reverse bias the photodiode, a current mirror, and a sigma-delta modulator configured to generate a digital output related to the received light and having a high resolution while using low power. The digital output could be used to determine a pulse rate or other properties of blood in the portion of subsurface vasculature by detecting absorption of ambient light by blood in the portion of subsurface vasculature. Components of the body-mountable device could be embedded in a polymeric material configured for mounting to a surface of an eye. The digital output and/or related information could be wirelessly communicated by the body-mountable device.
