This wearable ECG patch offers continuous heart monitoring while fixing common issues with current devices, such as bulky designs, short battery life, and missed data when signals are sent elsewhere for processing. By analyzing data directly on the device, it reduces power use and provides real-time heart rate, HRV, and irregular heartbeat information in a small, comfortable patch designed for long-term wear.
Background: Ambulatory ECG monitoring systems often require bulky hardware, frequent battery changes, or off board signal processing that causes data gaps, missed alerts, and degraded signal fidelity. Noise, motion artifacts, and static transmission schemes further reduce reliability, while few devices integrate real time analytics with adaptive power management in a discreet, wearable patch.
Technology Overview: This invention is a flexible two lead ECG patch powered by a CR2032 battery and implemented on a TI CC2640 microcontroller under TI RTOS. It acquires ECG at 400 Hz and performs real time artifact rejection using dynamic baseline matching and amplitude and frequency gating, followed by R peak detection and calculation of instantaneous heart rate and four time domain HRV metrics. Valid ECG segments and derived parameters are transmitted over secure BLE using ECC key exchange and AES 128 encryption, with dynamic transmit power control based on RSSI. Four power saving modes govern data transmission and sleep intervals, including event triggered modes that suppress artifact intervals and extend operating life to approximately 250 hours.
Advantages: • Provides continuous autonomous ECG monitoring with onboard analytics • Improves signal fidelity using real time noise and motion artifact rejection • Extends battery life through adaptive duty cycling and dynamic BLE power control • Reduces data transmission volume by suppressing artifact segments • Enhances security with ECC based key exchange and AES 128 encryption • Improves comfort via a thin flexible two lead adhesive patch design • Calculates HRV metrics on device to minimize external processing needs • Supports low cost disposable deployment with simple coin cell power
