SPE-003 flexibility thin film piezoelectric sensor is a highly sensitive sleep monitoring sensor, when it is installed on the mattress and roughly parallel to the chest or heart, the sensor can sense the human sleep heart rate, breathing, pulse and other dynamic signals and can generate micro-strain inside it, then generate electrical signals between the upper and lower electrode surfaces of the piezoelectric film. After the signal is amplified and filtered at the back end, the desired vital sign information is obtained through data processing. Sleep monitoring sensors can detect not only small changes in the body such as heart rate and breathing rate, but also larger movements such as turning over and getting out of bed. Users continuously monitor these signals during sleep which can not only record their deep and light sleep time, but also record the number of snoring and turning over, as a basis for assessing their sleep quality.
