ARRAYED ELECTRODES IN A WEARABLE DEVICE FOR DETERMINING PHYSIOLOGICAL CHARACTERISTICS
First Claim
1. A method comprising:
- selecting a subset of electrodes from a plurality of subsets of electrodes, the plurality of subsets of electrodes being disposed in a wearable device;
capturing a sensor signal including data representing a motion-related signal component and a physiological-related component;
generating a motion-related signal at a motion sensor in the wearable device;
reducing a magnitude of the motion-related signal component by an amount associated with the motion-related signal to yield the physiological-related signal component; and
deriving a physiological characteristic from the physiological-related signal component.

Abstract
Embodiments relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and wearable computing devices in capturing and deriving physiological characteristic data. More specifically, an array of electrodes and methods are configured to determine physiological characteristics using a wearable device (or carried device) that may be subject to motion. In one embodiment, an array of electrodes is disposed substantially in a wearable housing. At least a portion of the array including electrodes configured to either drive a first signal to a target location or receive a second signal from the target location. The second signal includes data representing one or more physiological characteristics. A sensor selector is configured to identify a subset of the electrodes adjacent to the target location and to select the subset of the electrodes from which to receive a sensor signal that includes data representing one or more physiological characteristics.
