Contactless RADAR Based Vital Sign and Heart Sound Measurement
*Live-Demo @ our Booth!*
ViRa24 is the RADAR system developed for the highly accurate measurement of vital signs, which include pulse, respiration and heart sounds. The latter in particular are of high medical relevance, as they allow particularly accurate measurement of the inter-beat intervals (elapsed time between successive heartbeats). These can also be used to make statements about stress levels or diseases of the autonomic nervous system.
The system was designed for R&D in such a way that it can be easily connected to an edge computing device (Nvidia Jetson Nano, Raspberry Pi, Google Coral...). This allows AI algorithms to be tested directly on the corresponding computing unit on the system. The extremely high-quality data is the result of years of research and development work.
ViRa24 is unparalleled and its features are unique:
- Developed for convenient communication with edge computing devices
- Plug-and-play USB data interface and software framework
- Highly accurate non-contact detection of vital signs including highly relevant medical heart sounds from up to 1 m away
- Radar technology proven in clinical studies
- Synchronous references can be connected (up to 4 analog inputs and a jack plug for e.g. a 2- or 3-channel ECG)
- RoHs conformity, CE marking and compliance with applicable radio standards
The system is supplied with a graphical user interface with open source code for evaluation. This contains the following features:
- Real-time display of
o the raw radar data
o the unprocessed distance data
o breathing and pulse movement
o the heart sounds
o the signal spectrum
o analog reference sensors
- Adjustable filtering and amplification
- Storage of all raw data
- Automatic offset compensation
