3D 프린팅으로 제작한 스트레인게이지를 이용한 어깨 모션 인식 시스템 개발
Abstract
Maintaining good health is a top priority for many people, particularly active seniors with a variety of physical activities. The shoulder is a complex joint that is particularly susceptible to injury, but it plays a crucial role in many physical activities. This study aimed to measure using a strain gauge manufactured by a 3D printer to detect shoulder motion. The sensor was fabricated using carbon nanotube (CNT) and nylon conductive filaments, and TPU filaments. The sensor in this paper was manufactured by printing three conductive lines on the main body printed with TPU. The manufactured sensor was attached to the shoulder to measure the motion of the shoulder. In this paper, we confirmed the possibility of detecting shoulder movement of sensors through experiments measuring three shoulder motions.
