TE Connectivity Sleep Monitor Sensor

The TE Connectivity 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).

Very low thickness, imperceptible on mattress
High open-circuit voltage sensitivity to dynamic strain
Can detect breathing, pulse and body movement
Ballistocardiographic (BCG) principle
