Researchers at IMEC (Belgium) and Holst Centre (Netherlands) have released a prototype of an electrocardiogram (ECG) necklace that monitors the condition of the heart for a long time, enabling patients to freely perform daily activities under surveillance for up to 7 days. Long. You can monitor the condition of your heart during daily activities by wearing an ECG necklace. This powerful, easy-to-use necklace is designed to withstand potential problems such as baseline drift, EMG (electromyogram) and motion artifacts, as well as high value and variable electrode impedance. This necklace utilizes IMEC's ​​proprietary ultra-low power analog readout ASIC, which relies on a low power commercial RF/microprocessor platform. A wavelet-based heartbeat detection algorithm is embedded in the processor, which can achieve 99.8% sensitivity and 99.77% prediction accuracy for the proprietary database of MIT-BIH database and walking ECG record. Even at very high noise levels, it can achieve a resolution of 1 sample when detecting heartbeats. It can still achieve satisfactory performance until the SNR (Signal to Noise Ratio) is equal to 0 dB. Long-distance data logging is possible through an optional memory module, and the second ultra-low-power microcontroller unit can wirelessly transmit ECG data to a computer within 10m.
