Abstract
Data about concentration of one or more types of molecules present within a human body are determined noninvasively using radio frequency (RF) signals. RF signals at several different frequencies and at very low power levels are emitted at different times from different antennas of a sensor device. In one implementation, an antenna array comprises five antennas in a quincunx arrangement. The sensor device may also include photoplethysmographs or other sensors. Signals from the sensor device are used to determine compensated data that compensates for motion of the sensor device with respect to the user. This motion may be transient, the result of the user repositioning the sensor device, and so forth. The compensated data may then be used to determine the concentration of one or more types of molecules within the user.
