Read aloud A new device should help prevent postural damage and thus back pain. It was now presented by two students of the Technical University of Darmstadt. The development of Ghaith Noman and Azam Mahmood is a small sensor that is attached to the back. If you take a posture that puts too much strain on the spine, the sensor starts to vibrate, encouraging you to take another position. The invention of the two information and electrical engineering students could help in the future to solve a serious problem, because back problems are now in Germany the common disease number one. Experts estimate that three-quarters of all 30- to 60-year-olds suffer from back pain. The main reason for this is malpractice, as reported by the Technische Universität Darmstadt. The medical-technical sensor, which should prevent such bad postures, is about as big as a USB stick. It is attached to the skin with special double-sided tape so that it is not visible under clothing. Before the device is put into operation, a doctor or technician first determines an ideal posture that is individually tailored to the respective user. This target state is stored on the sensor. A microcomputer then constantly compares the target and the actual back posture. If the deviation is in an unfavorable range for more than one minute, the vibration indicates that the malposition is correct. The operation of the little helper is very simple: A single button is used to switch on and off and to program the reference position.

The back sensor, however, can do even more: it also stores the user's posture throughout the day and week. "So in retrospect, it is possible to contrast the total time of the ideal, the back-sparing attitude of the total time of the wrong attitude and thus learning effects to observe, " said Noman. The device is also suitable for scientific studies. If you also integrated a GPS chip for satellite navigation, it would be possible to determine where most malpositions occur - for example, when sitting in the office. Then countermeasures could be taken. Currently Noman and Mahmood Partner are looking for the marketing of their invention. You can imagine that especially health insurance companies have a great interest in the sensor.
