20.500.12556/RUL-131095 Suitability of strain gage sensors for integration into smart sport equipment a golf club example Wearable devices and smart sport equipment are being increasingly used in amateur and professional sports. Smart sport equipment employs various sensors for detecting its state and actions. The correct choice of the most appropriate sensor(s) is of paramount importance for efficient and successful operation of sport equipment. When integrated into the sport equipment, ideal sensors are unobstructive, and do not change the functionality of the equipment. The article focuses on experiments for identification and selection of sensors that are suitable for the integration into a golf club with the final goal of their use in real time biofeedback applications. We tested two orthogonally affixed strain gage (SG) sensors, a 3-axis accelerometer, and a 3-axis gyroscope. The strain gage sensors are calibrated and validated in the laboratory environment by a highly accurate Qualisys Track Manager (QTM) optical tracking system. Field test results show that different types of golf swing and improper movement in early phases of golf swing can be detected with strain gage sensors attached to the shaft of the golf club. Thus they are suitable for biofeedback applications to help golfers to learn repetitive golf swings. It is suggested that the use of strain gage sensors can improve the golf swing technical error detection accuracy and that strain gage sensors alone are enough for basic golf swing analysis. Our final goal is to be able to acquire and analyze as many parameters of a smart golf club in real time during the entire duration of the swing. This would give us the ability to design mobile and cloud biofeedback applications with terminal or concurrent feedback that will enable us to speed-up motor skill learning in golf. smart sport equipment sensor selection strain gage sensors gyroscope accelerometer golf swing analysis pametna športna oprema izbira senzorjev strain gage senzorji žiroskop pospeškometer analiza golfskega zamaha true false true Angleški jezik Slovenski jezik Članek v reviji 2021-09-22 15:17:44 2021-09-22 15:17:45 2023-05-26 03:41:40 0000-00-00 00:00:00 2017 0 0 18 str. iss. 4, art. 916 Vol. 17 Apr. 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.39 1424-8220 10.3390/s17040916 11726676 RAZ_Umek_Anton_2017.pdf RAZ_Umek_Anton_2017.pdf 1 1056A520AC10888B5C295C54C1097A9E b92efedbada3fe34627c3232b61a2ead713e85f9684f540a80ed4dfae120bae7 8548b0dc-1ba7-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=148349 http://www.mdpi.com/1424-8220/17/4/916 1 3471ddd9-1ba7-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=148348 Fakulteta za elektrotehniko 0 0 0
