Aside from being slightly not safe for work, they describe an intriguing product for monitoring heart rate.
They claim they can get an "extremely accurate ECG" without electrodes contacting the skin. They pull this off using capacitive electrodes that can be made very small and only have to be very close to the body, but do not need to touch (touching probably works best though). What really blows me away about this claim is that the device itself is very small and self contained, which means the sensors have to be close together. They say they use three sensors for detecting heart rate. Likely one is the ground, while the other two are the left and right leads. But with the sensors so close together, the potential difference detected between the left and right leads must be very small. This system can only work if they can record signals with a very high signal to noise ratio. If it works as they advertise, that is very impressive.
Importantly, this is different from the optical sensor that I described in the last post. That sensor cannot give you direct information about the health of the electrical system of the heart or information about whether or not chambers of the heart are beating in synchrony. Since this system will have ECG information it could be used for those purposes.
This system is probably fairly vulnerable to motion artifacts and for exercise you probably will need a strap, but otherwise, it looks like a pretty plausible product. Since this is just in prototype form, we can't know for sure whether or not it really does work as advertised, but in my opinion, the product seems challenging but doable.
