The XK-Slim Sensor is a new innovation inspired by Xandar Kardian’s flagship XK300 sensor, which is an award-winning, FDA 510(k) cleared class II medical device. The XK-Slim Sensor features Xandar Kardian’s proprietary UWB (ultra-wide band) radar technology which safely detects macro (body motion), micro (breathing motion) and nano (heartbeat) vibration patterns that are constantly generated by our human bodies to accurately measure a patient's vital signs. However, what makes the XK-Slim Sensor unique is its design - the product features a rotatable extending “blade” that optimizes vital sign collection, making it Xandar Kardian’s most versatile sensor yet.
