A physicist at the National Institute of Standards and Technology and a researcher at the German National Metrology Institute have developed a miniature heartbeat sensor that will provide more accurate readings in the future than current instruments.
The sensor is about the size of a cube of sugar. It has the best magnetic shielding capability and detection accuracy in the world. It does not need to be in direct contact with the body. It can be detected about 5 mm from the left side of the chest to detect a normal heartbeat. This eliminates the need for previous ECG instruments to be connected to the probe, and the Superconducting Quantum Interferometer (SQUID) also records these signals to determine the accuracy of the sensor.
How accurate is this sensor? It eliminates electronic signal interference caused by geomagnetic fields and human body fluids, such as the ability to effectively eliminate fetal heart signals when detecting pregnant women. Scientists have begun to study how to reduce the cost of this system so that It is truly available for medical applications.
