Abstract
The intermodulation communication principle has recently
shown several advantages over other passive wireless
sensor readout techniques. The advantages include a large
readout distance and the possibility of using generic
sensor elements. In this paper, we derive an algorithm to
estimate the quantity measured by the wireless sensor
from its intermodulation response and verify the
algorithm experimentally with a passive wireless
inclinometer sensor operating at 860 MHz. The results can
be further used to realize a reader device for
intermodulation communication sensors, maximize its
operational parameters, and optimize the sensor structure
for the best readout resolution.
