1. A method for measuring optical signals by a wearable electronic device, comprising:
activating a first combination of optical sensors, the first combination of optical sensors comprising a set of transmitter sensors from a plurality of transmitter sensors and a set of receiver sensors from a plurality of receiver sensors of the wearable electronic device, wherein the plurality of transmitter sensors comprises at least one transmitter sensor of a first wavelength, at least one transmitter sensor of a second wavelength, and at least one transmitter sensor of a third wavelength, and wherein at least one optical sensor of the first combination of optical sensors is positioned under a protrusion on an inner surface of the wearable electronic device;
measuring, at the set of receiver sensors at a first time, one or more signals from the set of transmitter sensors;
determining a signal quality metric associated with the one or more signals; and
selecting a second combination of optical sensors for use at a second time based at least in part on the signal quality metric.
