Sleep Monitor Strip

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.
