Key result
A processing method based on time series similarity for array pulse wave signals demonstrated better consistency and stability compared to the highest amplitude value algorithm.
Why the study?
Existing methods for deriving one-dimensional pulse waves from sensor arrays suffer from low consistency due to sensor position shifts, and practical processing methods remain scarce.
