May support non-contact monitoring development; leaves open clinical validity and utility versus established methods.
A high-precision laser displacement sensor can detect heartbeat-induced body surface motions of approximately 0.1 mm, demonstrating potential for non-contact physiological monitoring.
Suzuki et al. (2012) studied this question.
