(Re-)Watch our Telecare webinar to learn about how mmWave sensors enables accurate contact-less vitals and fall detection

Following-up on our safety webinar whose recording was recently uploaded on ti.com?1?, a recurring question is how radar can be used to: 1. provide contact-less vitals signs. 2. detect a person falling

mmWave Sensors for vitals and fall

Contact-less vital sensing

The key consideration is that both breathing and heart beats will create small deviation of the chest and those movements can be measured by the radar?

and to measure these small scale vibrations/displacements, we measure the change in phase of the FMCW signal with time at the target range bin?

More details can be found online at?our vital signs lab

How to detect some one is falling

The key algorithmic concept being:

When a person falls from standing, the change in height is rapid enough to be seen as different than sitting and triggers a fall event

Further algorithmic details, source and binaries can be found in our?fall detection experiment [3]
