The design of the micro-ECG amplification circuit

Abstract

This essay discusses a potential method of designing a micro-wearable device that can effectively detect human heart conditions and provide real-time feedback. Compared to the traditional method of designing wearable devices, the core innovation in this new approach is the utilization of the DRL circuit for the extraction of common-mode signals. This device can filter out a significant amount of noise due to the low current and low voltage conditions. The low current and low voltage conditions under which this device operates contribute to its remarkable energy efficiency. Consequently, the device boasts a long-lasting battery, reducing the need for frequent recharges, which is often a significant inconvenience associated with wearable technology. In the meantime, the non-invasive nature of the ECG technology integrated into this wearable device ensures that wearers can go about their daily lives comfortably without causing discomfort, making it suitable for continuous heart monitoring without impeding peoples activities or affecting peoples overall comfort.
