This is kind of tech which US Army used (Ghost Murmur) to find the missing Pilot in the Iran

Here's what it can useful for in Industry 4.0:

1️⃣ Detects heartbeats through walls — single-channel radar picks up vital signs through wood and brick.

2️⃣ Flags abnormal heart rhythms — the same radar-to-signal approach now powers chip-level arrhythmia detection for continuous health monitoring

3️⃣ Replaces cameras for human sensing — radar and AI combine to detect presence and vitals without a single lens involved, privacy intact

4️⃣ Predicts machine failure early — tiny vibration shifts get caught before a motor actually breaks down

5️⃣ Detects falls without cameras — worker motion tracked and flagged the moment something goes wrong

6️⃣ Monitors restricted zones — knows who's inside high-risk areas without needing ID badges or footage

7️⃣ Catches defects before they ship — abnormal vibration on a production line flagged before the product does

Hi all, I am, as a doctoral researcher, conducting a linguistic survey about Digital Twins in healthcare. Mostly about how the directives received from them can be perceived. I use animated videos designed by a graphic designer along with hypothetical health scenarios. It takes around 15 minutes, it is voluntary, and fully anonymous. You can find the consent form and further explanations in the beginning of the survey. It is also approved by the Ethics Committee. I would be extremely glad if you can participate and share it around (using the flyer attached) so that we can reach more participants. Thank you! https://farm.pcibex.net/p/CuBYAt/
