> The key enabler underlying EQ-Radio is a new algorithm for extracting the individual heartbeats from the wireless signal at an accuracy comparable to on-body ECG monitors.
I'm wondering: could this technology be used to detect contraction of other muscles than the heart? Like performing a wireless EMG?
Imagine holter monitors that can sit beside your bed as you sleep (tossing and turning), instead of wearing them, or instant continuous ECG data during triage.
Many heart attacks are misdiagnosed (especially in women) and instant continuous ECG readings (possibly from multiple people at once) would be incredible!
In case you were interested in the frequencies they were sweeping though:
We reproduced a state-of-the-art FMCW radio designed
by past work on wireless vital sign monitoring [7]. The
device generates a signal that sweeps from 5.46 GHz to
7.25 GHz every 4 milliseconds, transmitting sub-mW power.
The parameters were chosen as in [7] such that the transmis-
sion system is compliant with FCC regulations for consumer
electronics
I wonder if you can use lower frequencies? Since we are surrounded by radio waves maybe you can use use on those cheap SDRs and look for the 50-150hz space to see if you can pick up heart rate.
