智能睡眠監測薄膜帶
智能睡眠監測薄膜帶.pdf
The sleep monitor strip is a strip of Piezo film (piezoelectric PVDF polymer) 800mm long and 8mm wide. The active electrode area is 698.5mm long and 3mm wide. The total thickness of the strip is around 50 microns, making it extremely flexible and entirely imperceptible when placed under the body. Electrical interconnection is made via two crimped solder tabs. The strip produces a charge or voltage output when subjected to dynamic strain (change in length). When mounted across a mattress in line with the chest/heart, the strip can detect heart sounds, tiny changes in load or center of gravity due to breathing. These signals may then be assessed over an extended time period (e.g. overnight) and may be indicative of duration, phase, or quality of sleep.
The sensor requires no external power and is therefore suitable for use with battery-operated equipment where power consumption must be kept to a minimum.
