Mobile integrated electrode multifunction sensor and method
An integrated multifunction sensor, a mobile integrated sensor device, and process are described that include a sensor, where the sensor is used primarily for a first purpose other than as an electrode. In an implementation, an integrated multifunction sensor includes a multifunction sensor configured as a sensor and a first electrode, the multifunction sensor including a lid coupled to a first side of the sensor, where the lid includes a semi-conductive material, and an analog device connected to the lid; where the multifunction sensor is configured to couple to a controller that receives health information from the first electrode and a second electrode. In some embodiments, the integrated multifunction sensor can include an integrated optical sensor. In some implementations, a second electrode may be located elsewhere in a mobile integrated sensor device and complete a differential circuit.
1. An integrated multifunction sensor, comprising:
an optical sensor;
a lid wherein a first section of the lid comprises a material operable to transmit visible and near infra-red (IR) wavelengths and a second section of the lid comprises a semi-conductive material operable to transmit IR wavelengths and further operable to conduct electrical signals when contacted by a person's body;
a first electrode operable to detect electrical signals when the lid is contacted by a person's body;
an analog device connected to the lid, the analog device comprising an amplifier configured to detect changes in electrical potential when the lid is contacted by the person's body;
a second electrode operable to complete a differential circuit when the lid and the second electrode are simultaneously contacted by the person's body; and
a controller operable to receive information from the optical sensor, the first electrode, the analog device and the second electrode and output health information about a user.
2. The integrated multifunction sensor as recited in claim 1 , further comprising at least one of: a temperature sensor, a gas sensor, an infrared sensor, a pulse sensor, a flash sensor, an EKG sensor, or a proximity sensor.
3. The integrated multifunction sensor as recited in claim 1 , wherein the lid includes at least one of silicon or germanium.
4. The integrated multifunction sensor as recited in claim 1 , wherein the analog device receives an indication of changes in electrical potential in a person's body.
5. The integrated multifunction sensor as recited in claim 1 , wherein the controller is configured to determine an electrocardiogram using body electrical potential changes detected by the multifunction sensor.
6. The integrated multifunction sensor as recited in claim 1 , wherein the integrated multifunction sensor is configured for use in at least one of a wearable, a mobile phone, or a watch.
