A heartbeat detector<\/b> is a biomedical instrument that plays a crucial role in health monitoring systems<\/b>, used to measure a person\u2019s pulse rate<\/b> non-invasively. These devices are designed to detect the small physical or optical changes in the body caused by the rhythmic contraction and expansion of the heart<\/b>.<\/p>\n
The most common method uses a pulse sensor<\/b> with a photoplethysmography (PPG)<\/b> principle:<\/p>\n Other methods use piezo sensors<\/b> that detect pressure changes in the arteries, or even ECG electrodes<\/b> for higher accuracy.<\/p>\n Heartbeat detectors can be standalone devices or part of larger systems, such as fitness trackers<\/b>, smartwatches<\/b>, or patient monitoring systems.<\/b><\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" A heartbeat detector<\/b> is an essential device for monitoring heart health, providing real-time data about a person\u2019s pulse rate.
