Abstract: Disclosed herein are systems, devices, and apparatuses for wireless-enabled micromotion sensing. The wireless-enabled micromotion sensing system causes a transmit antenna to wirelessly transmit a series of probe transmissions and causes a receive antenna to wirelessly receive a series of reflected signals from the probe transmissions, where each reflected signal of the series of reflected signals corresponds to a corresponding transmission of the series of probe transmissions. The wireless-enabled micromotion sensing system determines a characteristic dataset comprising a change in a channel characteristic over time as between the series of reflected signals and the series of probe transmissions. The wireless-enabled micromotion sensing system determines based on the characteristic dataset whether the series of reflected signals is indicative of a periodic micromotion of an object.
