Xandar Kardian · Ambient, predictive health monitoring

Health is on our radar.

We make the XK300, the sensor that measures heart rate and breathing through the air, from the wall, all night, with nothing worn. FDA-cleared since 2021. On hospital wards, in nursing homes, in homes and in correctional facilities, and now in a consumer product of its own.

How it works, in one minute

A pulse goes out. The chest answers.

The XK300 sends an ultra-wideband radar pulse at a very low power, in the same frequency range as Wi-Fi, and reads the movement of the chest as it comes back: the rise of breathing, and under it, the beat of the heart. Through a duvet. Through a mattress. Nothing on the person.

Every reading is compared with the person's own recent nights, not a textbook range. That is the idea the company was built on, and the reason care teams notice change early.
