I'm doing some experiments with a wearable Galvanic Skin Response recorder. This measures emotional and arousal levels from the sweat glands on palms of hands. It's established engineering. I can't find a commercial wearable 24/7 version so I built one based on a Lascar data logger, op-amp buffer and some electrodes on the palms of my hands.
I have designed a wearable camera with sensors, that captures images when "interesting" events occurs, around 2000 images a day. The camera is triggered by movement, light, heat, etc from a person and when played back fast gives a recording of your day. The plan is to see when I'm (& patients) aroused by events/ images etc and sync camera images to the GSR. All is fun so far, e.g. the startle response my phone rings, and my response if I'm in a meeting with people. My request is, is there a commercial GSR logger that can be worn, as I want something a bit more elegant and practical to give to third parties? I've searched Google but seen nothing. We will buy several of these devices.
This is medical research financed by a software company, I can give you more details if interested, it's in the public domain.
