The PC 100 PostureControl trains sitting posture in order to prevent back pain. The small, flat clip can be attached discreetly to the neck of a garment and connects to a smartphone via Bluetooth. Smart algorithms automatically detect and analyse micromovements, upright phases, changes in position and active pauses. If the posture is too static, the clip will vibrate so that the user is able to change their position. The data can be retrieved and evaluated using the 8sense app.
