I am looking for a solution regarding the gsr, accelerometer, heart rate, skin temperature. From this other question seems that Grove isn't clear enough with their documentation. So I am looking for other ideas. I already know cooking hacks and I am afraid that with their hardware I can't make my Arduino wearable and comfortable enough, because at the end I'd like to attach a lithium battery with a case (that's why I don't want the extra bulk of a shield).
More details of what I am looking for.
Accelerometer: Range: +/- 1.0g Minimum resolution: 0.01g
Galvanic Skin Response Range: 56k Ohms to 20M Ohms Two-standard-deviation error of +/- 4.0% otherwise
Skin Temperature Range: 20.0°C to 40.0°C Resolution: 0.05°C Error: +/- 0.8°C
