Abstract
A blood pressure measurement method using at least one radar in a blood pressure measurement apparatus may comprise: measuring a radar signal for at least one body part; extracting a heartbeat signal from the radar signal; selecting one or more peak signals from the heartbeat signal; calculating an area under a curve (AUC) of each of the selected one or more peak signals; and calculating blood pressure from the calculated AUC on the basis of a derived relational expression between AUC and blood pressure.
Claims10
A blood pressure measurement method using at least one radar in a blood pressure measurement apparatus, comprising:
- measuring a radar signal for at least one body part;
- extracting a heartbeat signal from the radar signal;
- selecting one or more peak signals from the heartbeat signal;
- calculating an area under a curve (AUC) of each of the selected one or more peak signals;
- and
- calculating blood pressure from the calculated AUC on the basis of a derived relational expression between AUC and blood pressure.
A blood pressure measurement apparatus using at least one radar, comprising:
- a heartbeat signal extraction unit configured to extract a heartbeat signal from a radar signal reflected by at least one body part through the at least one radar;
- and
- a blood pressure measurement unit configured to calculate a parameter to be used for measuring blood pressure from the heartbeat signal and calculate the blood pressure from the parameter,
- wherein the blood pressure measurement unit selects one or more peak signals from the heartbeat signal, calculates an area under curve (AUC) of each of the selected one or more peak signals, and calculates the blood pressure using the calculated AUC corresponding to the parameter.
