Why the study?
Ballistocardiogram signals from optical fiber sensors are difficult to detect due to differential detector effects, self-interference, installation variation, individual differences, and body interferences.

Supports the feasibility of contactless vital sign monitoring via optical fiber mattresses; leaves open whether this accuracy persists in.
Does an optical fiber sensor mattress with adaptive regulations accurately estimate heart and respiration rates compared to conventional medical monitors in healthy volunteers?
An optical fiber sensor integrated into a mattress can accurately estimate heart and respiration rates under various posture conditions without direct skin contact.
