Innovation : iCard ECG Monitors your Heart on your iPhone
Now thats called innovation. The new iCard ECG uses an iDevice to monitor your heart through any clothing you may be wearing, It attaches to the back of your iPhone with a velcro strap and sends ECG data to an app on the device.
With the device attached to you iPhone just hold the mix to your chest and voila instant heart rate. Surprisingly there are already apps in the iOS AppStore and Android Market place that monitor your heart rate using the camera and flash on your portable smartphone, but those can be highly inaccurate.
