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.
