20.500.12556/RUL-129626 MC sensor-a novel method for measurement of muscle tension This paper presents a new muscle contraction (MC) sensor. This MC sensor is based on a novel principle whereby muscle tension is measured during muscle contractions. During the measurement, the sensor is fixed on the skin surface above the muscle, while the sensor tip applies pressure and causes an indentation of the skin and intermediate layer directly above the muscle and muscle itself. The force on the sensor tip is then measured. This force is roughly proportional to the tension of the muscle. The measurement is non-invasive and selective. Selectivity of MC measurement refers to the specific muscle or part of the muscle that is being measured and is limited by the size of the sensor tip. The sensor is relatively small and light so that the measurements can be performed while the measured subject performs different activities. Test measurements with this MC sensor on the biceps brachii muscle under isometric conditions (elbow angle 90°) showed a high individual linear correlation between the isometric force and MC signal amplitudes (0.97 ≤ r ≤ 1). The measurements also revealed a strong correlation between the MC and electromyogram (EMG) signals as well as good dynamic behaviour by the MC sensor. We believe that this MC sensor, when fully tested, will be a useful device for muscle mechanic diagnostics and that it will be complementary to existing methods. biomechanics skeletal muscles muscle force contractile properties measuring techniques biophysics biomehanika skeletne mišice mišična sila kontrakcijske lastnosti merilne tehnike biofizika true false true Angleški jezik Slovenski jezik Članek v reviji 2021-09-06 10:11:26 2021-09-06 10:11:26 2022-09-08 04:09:41 0000-00-00 00:00:00 2011 0 0 Str. 9411-9425 iss. 10 Vol. 11 Oct. 2011 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 612:57:53 1424-8220 10.3390/s111009411 8712276 RAZ_Djordjevic_Srdjan_2011.pdf RAZ_Djordjevic_Srdjan_2011.pdf 1 677A5BD3D524A369EADECC33706E03B1 cbabfad9d9ffb257331ae20a7b54d8bd7a3fa2bea180d262bd4dfa5327c0c897 1f2e0a8d-0eea-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=146640 https://www.mdpi.com/1424-8220/11/10/9411 0 085a7054-0eea-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=146639 Fakulteta za elektrotehniko 0 0 0
