EMFIT QS relies on ballistocardiography, a technique for sensing the sudden ejection of blood into the great vessels with each heart beat, and breathing movement analysis.

Emfit’s proprietary ferro-electret sensor technology is super sensitive and thus allows placement even under a very thick memory foam mattress. 


The electro-active material itself is self-biased and does not use any power. Only the small electronics placed on the floor uses electricity and has the wireless WI-Fi or cellular data transceiver.

Under-mattress placement ensures longevity for many years use without need to regular replacement.

Automatic measuring - sleep data is available after user leaves the bed in the morning.

Autonomous measuring - there is no phone needed in operation. Device has its own processor and buffer memory!
