I am looking for a watch or chest strap heart rate monitor that has battery for ~24 hours and can export raw data to a CSV or excel file. Many of the watches (fitbit, garmin etc.) seem to monitor continuously but lack the function to export the data as a raw file.
It is for research into a drug for anxiety using HR and questionnaires as a measure of anxiety.
Polar chest strap should do the job. It comes with its software or connects to a polar watch which can export data as a csv.
Another one is Whoop 3.0. Provides 100 samples per second continuous measurements and many have now been able to export data
Dear Alexander Gallo ,
as Sebastian Möck mentioned, the Acentas system exports raw data and I have also had good experience with it. However, it relies on chest straps and wearing those for 24h is not very comfortable. As you stated correctly, most commercial system do not provide the possibility to export raw data if you do not know the API. There are solutions to overcome this but they require some technical knowledge.

Hi Alexander,
I would strongly suggest you checkout Empatica's E4 device. It's a wrist-worn device that looks like a watch and measures several biosignals that you can easily read out after recording using an USB (or with BLE if you prefer). One of these signals is the PPG which you can use to extract pulse/heart rate yourself, although I believe the system can also calculate it for you if you wish.
Another of the biosignals it measures is electrodermal activity (EDA), which is a peripheral nervous signal looking at how the autonomic state produces changes in skin conductivity (e.g. sweat response). It could be very interesting for your anxiety work.
Since it's a wrist-worn device that looks almost like a watch is very discrete and non-obtrusive, so its presence shouldn't influence participant response.
Best,
Rafael
