– The Firstbeat Body Guard has a White Paper for validation:

https://assets.firstbeat.com/firstbeat/uploads/2015/10/white_paper_bodyguard2_final.pdf

it has 67 citations since 2013

– The Bitalino Biomedical Toolkit also has a validation paper:

https://mdpi-res.com/d_attachment/sensors/sensors-21-04485/article_deploy/sensors-21-04485-v2.pdf?version=1625205535

it has 1 citation since 2021

– The Biosignalsplux Solo 16 bit data acquisition system does not need a validation paper, since it has 16-bit resolution as clinical ECG devices.

The Firstbeat Body Guard is a well established device:

– Unfortunately, software support for the Firstbeat Body Guard is very poor, and strongly limited to the proprietary software of Firstbeat.

– The Firstbeat Body Guard has no live-streaming option like MQTT

– There can examples be found where the Bitalino Biomedical Toolkit is used for MQTT applications.

– The Biosignalsplux Solo 16 bit has a Matlab Toolbox, etc. generally excellent software support

– The Bodyguard seems to be easily used 24 *7

– What about the Biosignalsplux Solo 16 bit or the Bitalino Biomedical Toolkit?

– We could not find any example use case for this

– There is no data storage for these devices. They need to connected to a phone with an app

– such a storage card device could eventually be added, as far as we know

– one can image that a Bitalino Biomedical Toolkit or a Biosignalsplux Solo 16 bit can be taped to the body to be a BodyGuard repacement

An interesting experiment would be a 24 * 7 recording of a Bitalino Biomedical Toolkit, a Biosignalsplux Solo 16 bit, a Polar OH1 and a Verity Sense to see whether they differ in accuracy and wether it is possible to get stable recordings and an easy transfer of sensor data to Home Assistant.

What is the definition of a «research grade device»

A research grade device is a device which scientists use for research. The longer the list of publications in which it is used in, the better. And the higher the quality of the publications in which it is used in also. This has also has to be concidered when deciding about a reference ECG Device to choose.
