A w-band MMIC radar system for remote detection of vital signs
Autor: Diebold, S., Ayhan, S., Scherr, S., Massler, H., Tessmann, A., Leuther, A., Ambacher, O., Zwick, T., Kallfass, I.
In medical and personal health systems for vital sign monitoring, contact-free remote detection is favourable compared to wired solutions. For example, they help to avoid severe pain, which is involved when a patient with burned skin has to be examin
