There are fitness trackers that help monitor your pulse and assess your health, but most of them require you to move around with an awkward thing strapped to your wrist or chest. The Darma smart cushion, however, only requires that you sit on it. Utilizing thin 1mm sensors that can detect even the tiniest body movements, the Darma will communicate your heart rate, respiratory patterns and even your sitting posture to an accompanying iOS app via Bluetooth 4.0.
