For a research project, we are looking to record participants' heart rate and skin conductance as unobtrusively as possible (no cables, electrodes, stickers), and are planning to correlate them to other measures. Going from the literature, the E4 by Empatica seemed to be the gold standard, but that device has been discontinued and the successor is extremely expensive (2500 $ per device).
Does anyone have any recommendations? There is obviously a mountain of Smartwatches and Fitbits and whatnots out there, but very often recording quality is poor and/or raw data is not accessible.
Any help, be it ideas, brands, papers, other places to ask this question, would be so very appreciated.
I actually have the same question/struggle, so I'm following this topic with interest...
One possible interesting sensor could be the emotibit: https://shop.openbci.com/
Hi Manon, maybe the Nowatch is also an option? It includes heart rate and skin conductance, and most of the raw data is available for the user: https://nowatch.com/

Hi Manon, Hi Peter,
thank you both for your suggestions!
We had indeed also been looking at the Nowatch Peter suggested, but ended up making the decision to go with the Shimmer3 GSR+ (https://shimmersensing.com/product/shimmer3-gsr-unit/), despite the fact that it has some cables that will run along the participants' fingers, which we were originally hoping to avoid.
We chose to go with that one on account of a second project that would be using the same equipment with less constraints.
Best, and thanks to you both again,
Janna
Hi Janna,
We are actually quite experienced with the shimmer. It's a nice device/platform.
We did some experiments (in the lab) trying out different bodily locations under baseline and stress conditions. We compared dry electrodes on the left hand fingers ('default setup by shimmer' by using wet electrodes on the shoulders (central part of the trapezius transverse part (left and right) the central part of the rear deltoid (left)). Although I still have to analyze the data on a detailled level, first analyses suggest that measuring on the shoulder is a promising alternative for the fingers.
