Key result
Cuffless blood pressure estimation using pressure pulse wave signals from a single piezoelectric sensor achieved mean errors of 0.70 ± 7.78 mmHg for systolic and 0.83 ± 5.45 mmHg for diastolic pressure.
Why the study?
Pulse transit time methods for noninvasive cuffless blood pressure measurement require two sensors to collect two-channel signals, making wearable device deployment inconvenient.
Does cuffless blood pressure estimation using single-site pressure pulse wave signals accurately measure blood pressure compared to oscillometric techniques in middle-aged and elderly participants?
Observational (n=65)
Does cuffless blood pressure estimation using single-site pressure pulse wave signals accurately measure blood pressure compared to oscillometric techniques in middle-aged and elderly participants?
A single-site piezoelectric sensor measuring pressure pulse wave signals provides accurate cuffless blood pressure estimation, offering a convenient alternative for home monitoring.

Supports single-sensor cuffless BP estimation in middle-aged/elderly adults; hypothesis-generating and requires prospective validation before clinical adoption.
Liu et al. (2018) conducted an observational in Blood pressure estimation (n=65). Pressure pulse wave (PPW) signals from a single piezoelectric sensor vs. Conventional PTT-based method and oscillometric technique was evaluated on Mean error for estimated systolic and diastolic blood pressure. Cuffless blood pressure estimation using pressure pulse wave signals from a single piezoelectric sensor achieved mean errors of 0.70 ± 7.78 mmHg for systolic and 0.83 ± 5.45 mmHg for diastolic pressure.
