People in many professions suffer from low back pain (LBP) due to wrong movements. Although this is anticipated by occupational medicine, the quality of evidence is low, since little objective measurements about the spine position in daily-use exist. The paper presents an ultra-flat posture monitoring system based on low-cost acceleration sensors, which can be very efficiently be used to measure the posture of the spine. First experiments (lab-based and in daily-use) showed a deviation of approximately 1° with a low standard deviation. Innovation is the suitability for daily-use by sensors having a height of 2,5 mm that allow a seamless usage even during positions applying pressure to the back such a leaned sitting on a chair.
