Summary of APPSENS’S BLE WEARABLE ECG SENSOR POWERED BY NORDIC NRF52832 DETECTS ARRHYTHMIA
The ECG247 Smart Heart Sensor by AppSens is a wearable Bluetooth-enabled ECG monitor designed to detect atrial fibrillation and other arrhythmias. It consists of a disposable electrode patch and a reusable electronic module powered by Nordic’s nRF52832 SoC, featuring a 64MHz ARM Cortex M4 processor with FPU. This low-power device enables continuous heart monitoring for up to 14 days on a single coin-cell battery, facilitating self-diagnosis even during physical activity.
Parts used in the ECG247 Smart Heart Sensor:
- Nordic nRF52832 SoC (64MHz ARM Cortex M4 with FPU)
- Disposable electrode-patch
- Reusable electronic component/module
- CR2032 coin-cell battery
AppSens, a Norway-based medical technology manufacturer, designed ‘ECG247 Smart Heart Sensor‘ – a Bluetooth LE enabled wearable ECG sensor, powered by Nordic’s nRF52832 SoC, to detect irregular heartbeats. This device is a wearable electrocardiographic (ECG) heart monitor designed to detect atrial fibrillation and other major cardiac arrhythmias. Atrial fibrillation is the most commonly occurred cardiac rhythm disorder and is a common cause of stroke.
ECG247 Smart Heart Sensor has two parts – a disposable electrode-patch to fasten the sensor to the patient’s chest and a reusable electronic component for measuring the ECG signal. The patient can use this solution to self-diagnose their heart condition. This can also be used during exercise/physical activity.
The brain of this ECG247 Smart Heart Sensor is an nRF52832 SoC, based on a 64MHz, 32-bit ARM Cortex M4 processor with a floating-point unit (FPU). This processor is capable of handling the proprietory algorithm for continuously measuring and analyzing the electrical activity in the patient’s heart and detect any irregularity in the rhythm. Such complex algorithms need fast and accurate floating-point operations – here comes the powerful FPU of nRF52832. The nRF52832 is an ultra-low-power SoC that draws only a 5.5mA peak current while transmitting or receiving over the 2.4GHz band. This lets the patch run continuously for 14 days with a single CR2032 coin-cell battery.
