Abstract
An apparatus for extracting a cardiovascular characteristic is provided. The apparatus may include: a first sensor configured to measure a vibration signal generated by a pulse wave of a subject; a second sensor configured to measure a pulse wave signal of the subject; a processor configured to perform an operation related to a cardiovascular characteristic on the basis of the measured vibration signal and pulse wave signal; and a main body in which the first sensor, the second sensor, and the processor are mounted.
Claims31
An apparatus for extracting a cardiovascular characteristic, the apparatus comprising:
- a main body, a first sensor mounted to the main body, a second sensor mounted to the main body, and a processor mounted to the main body;
- wherein:
- the first sensor is configured to measure a vibration signal generated by a pulse wave of a subject;
- the second sensor is configured to measure a pulse wave signal of the subject;
- the processor is configured to calculate a cardiovascular characteristic based on the measured vibration signal and pulse wave signal.
An apparatus for extracting a cardiovascular characteristic, the apparatus comprising:
- a main body;
- at least one strap connected to the main body and configured to be wrapped around a wrist of a subject;
- a first sensor mounted to the main body and comprising one of a force sensor and a strain gauge configured to measure a contact pressure signal of the subject generated by a vibration that is transferred to the main body through the at least one strap when a pulse wave is generated;
- a second sensor mounted to the main body and configured to measure a pulse wave signal of the subject;
- and
- a processor mounted to the main body and configured to calculate a cardiovascular characteristic based on the contact pressure signal and the pulse wave signal.
An apparatus for extracting a cardiovascular characteristic, the apparatus comprising:
- a main body;
- at least one strap connected to the main body and configured to be wrapped around a wrist of a subject;
- a first sensor mounted to the main body and comprising a microphone configured to measure a sound wave signal generated by a vibration that is transferred to the main body through the at least one strap when a pulse wave is generated;
- a second sensor mounted to the main body and configured to measure a pulse wave signal of the subject;
- and
- a processor mounted to the main body and configured to calculate a cardiovascular characteristic based on the sound wave signal and the pulse wave signal.
A method of extracting a cardiovascular characteristic by a cardiovascular characteristic extracting apparatus comprising a main body to which a first sensor and a second sensor are mounted, the method comprising:
- the first sensor measuring a vibration signal generated by a pulse wave of a subject;
- the second sensor measuring a pulse wave signal;
- and
- calculating a cardiovascular characteristic based on the vibration signal and the pulse wave signal.
