Abstract
Wearable devices are described herein including at least two sensors configured to detect hemodynamic properties of a wearer. A first sensor is configured to detect a hemodynamic property of a portion of vasculature, where the operation of the first sensor is based on a hemodynamic property detected by a second sensor. A timing of operation, a value of one or more controlled operational parameters, a filter setting, or some other aspect of the operation of the first sensor could be controlled based on the hemodynamic property detected by the second sensor. Hemodynamic properties could include blood flow rate, volume, and/or pressure in one or more portions of vasculature, a timing, rate, delay, or other information about heartbeats, an oxygenation level of blood, a velocity of blood cells in blood, or some other information about a wearer's blood, heart, and/or cardiovascular system.
