본 발명은 폴리머 수지에 다중벽 탄소나노튜브(MWCNT)와 같은 전도성 나노 입자와 자기장의 세기를 조절할 수 있는 CIP(carbonyl iron powder) 등을 혼합하여 신체 또는 로봇 등의 움직임을 모니터링할 수 있는 고신축성 고분자 복합체 스트레인 센서 및 그 제조 방법에 관한 것으로, 본 발명에 따른 고신축성 고분자 복합체 스트레인 센서는 폴리머 수지에 전도성 나노입자와 자기장의 세기를 조절할 수 있는 CIP(carbonyl iron powder)와, 상기 폴리머 수지 내에서 전도성 나노입자의 분산을 위한 분산제로서 PSS(Polysodium 4-styren sulfonate)가 혼입된 고분자 복합체로 만들어진다. The present invention relates to a highly stretchable polymer composite strain sensor and a manufacturing method therefor, the sensor being capable of monitoring the movement of a body, a robot and the like by mixing, in a polymer resin, conductive nanoparticles such as multi-walled carbon nanotubes (MWCNTs), carbonyl iron powder (CIP), which can control the intensity of a magnetic field, and the like. The highly stretchable polymer composite strain sensor according to the present invention is manufactured from a polymer composite in which conductive nanoparticles, CIP, which can control the intensity of a magnetic field, and polysodium 4-styrene sulfonate (PSS), which is a dispersant for dispersing the conductive nanoparticles in a polymer resin, are mixed in the polymer resin.
