Biosensors with ECG function for heart rate monitoring in wearables

Graham Prophet @ eedesignnewseurope.com writes:

Silicon Labs has introduced a family of optical biometric sensors providing advanced heart rate monitoring (HRM) by transcutaneous optical measurements, along with electrocardiogram (ECG) capabilities, for a range of wearable fitness and wellness products.

Si117x sensor modules combine ultra-low power, high sensitivity and integration, for smart watches and wrist-based, patch-type and other wearables requiring long battery life and enhanced HRM accuracy. To simplify development and speed time to market, Silicon Labs offers a complete, end-to-end sensing solution featuring the Si117x sensor module, HRM algorithm, Wireless Gecko SoCs for Bluetooth connectivity, and a wrist-based development kit with sample code and example projects.

HeartyPatch – Open source ECG patch with Wifi

An ECG patch with HRV monitoring that’s open source, affordable, and Wi-Fi/Bluetooth connected.

HeartyPatch is a completely open source, single-lead, ECG-HR wearable patch with HRV (Heart Rate Variability) analysis. It is based on the popular ESP32 system-on-a-chip. By using low-cost, highly-integrated components, we are able to keep the BOM’s cost low, while the simplicity of the circuit design means future expansion will be easier. HeartyPatch can be used both as a lifestyle device for managing fitness and stress as well as for diagnostics and medical research, with the potential for even more interesting applications.

Design and Implementation of a 12 Lead Portable ECG

Alex Lao and his team at McMaster University have developed a compact, battery powered, 12-lead electro-cardiogram:

During the academic year of 2016-2017 at McMaster University, in conjunction with Dr. DeBruin, Christina Riczu, Thomas Phan and Emilie Corcoran, we developed a compact, battery powered, 12-lead electro-cardiogram. The project won 1st place in the biomedical category at the ECE Capstone Poster Day.

Using HealthyPi with a PC for ECG,Respiration & SpO2

Ashwin K Whitchurch, Venkatesh Bhat, and Manikandan S @ hackster.io build a PC based ECG,Respiration & SpO2 monitor.

We introduced the HealthyPi as a HAT add-on for the Raspberry Pi, turning it into a full-featured, medical-grade open patient monitor. However, we realized later that people also wanted to use the board standalone with a Windows/Linux/Mac PC. We already had an on-board USB port from the SAMD21 on the board.

DIY ECG with 1 op-amp

A DIY ECG made from single op-amp (LM741) and 5 resistors by Scott Harden:

I made surprisingly good ECG from a single op-amp and 5 resistors! An ECG (electrocardiograph, sometimes called EKG) is a graph of the electrical potential your heart produces as it beats. Seven years ago I posted DIY ECG Machine on the Cheap which showed a discernible ECG I obtained using an op-amp, two resistors, and a capacitor outputting to a PC sound card’s microphone input.

ECG Arduino Shield

FIPX3OLIMRYIOBF.LARGE

This project is an Arduino shield able to measure ECG and respiration. The shield is equipped with a LCD display to show measured signal in real time. It’s based on ADS1292R ECG Front End from TI.

Recently i made shield for arduino which can measure ECG, respiration, eventually after some changes in PCB and code, EEG and EMG. Big advantage of this shield is possibility to make it easily at home. The shield is equipped by display to show you measured signal real-time.
