Description

동적분석을 위한 스트레인 센서, 그 스트레인 센서의 제조방법Strain sensor for dynamic analysis, manufacturing method of the strain sensor
본 발명은 동적분석을 위한 스트레인 센서, 그 스트레인 센서의 제조방법에 관한 것으로, 보다 상세하게는 관절의 움직임에 따른 정보 수집이 필요한 스포츠에서의 동적분석을 위한 스트레인 센서에 관한 것이다.The present invention relates to a strain sensor for dynamic analysis, and a method for manufacturing the strain sensor, and more particularly, to a strain sensor for dynamic analysis in sports that requires information collection according to movement of a joint.
섬유(fiber)를 기반으로 하는 전자소자는 아직 개념적인 단계이지만, 섬유의 신축(stretching)과 직조의 가능성, 넓은 표면적, 표면 처리의 다양성, 복합재료 구성의 용이성과 같은 다양한 장점으로 인하여 많은 전자소자 시장을 대체할 가능성이 높다. 가능한 섬유 기반의 전자소자로서 텍스타일 태양전지, 신축성 트랜지스터, 신축성 디스플레이, 외부 자극형 약물 전달, 바이오 센서 및 가스 센서, 광조절 기능성 섬유, 기능성 의류, 방위 산업용 기능성 제품 등을 예로 들 수 있다.Although electronic devices based on fibers are still in a conceptual stage, many electronic devices due to various advantages such as the possibility of stretching and weaving of fibers, wide surface area, diversity of surface treatment, and ease of composition of composite materials It is likely to replace the market. Examples of possible fiber-based electronic devices include textile solar cells, stretchable transistors, stretchable displays, external stimulus drug delivery, biosensors and gas sensors, light-regulating functional fibers, functional clothing, and functional products for the defense industry.
섬유 기반의 전자소자에 사용되는 전도성 나노 섬유의 경우 전도성을 유지하면서 넓은 신장 범위를 확보하는 것이 유리하다. 종래의 매트릭스와 전도성 물질의 복합체 형태의 전극은 원하는 전도도를 얻기 위해 다량의 전도성 물질이 필요하다. 그러나 전도성 물질의 비율이 늘어날 경우 전도도는 향상하나 매트릭스의 탄성 특성이 감소하여 복합체의 신축성이 감소하게 된다.In the case of conductive nanofibers used in fiber-based electronic devices, it is advantageous to secure a wide elongation range while maintaining conductivity. The electrode in the form of a composite of a conventional matrix and a conductive material requires a large amount of conductive material to obtain a desired conductivity. However, when the proportion of the conductive material is increased, the conductivity is improved, but the elastic properties of the matrix are reduced, thereby reducing the elasticity of the composite.
신축성 유연 전극(stretchable electrode)은 인공 전자 피부, 휘는 디스플레이, 인장 센서와 같은 다양한 분야들에 적용되고 있다. 최근에 건강 재활 치료, 개인 건강 모니터링, 구조 결함 모니터링, 스포츠 선수 성능 모니터링 등 다양한 인장 센서의 잠재적 응용처가 재조명됨에 따라, 유연하면서 신축성 있고 동시에 인장에 따라 민감한 인장 센서에 관한 연구가 활발하게 진행되고 있다. 특히, 고신축성·고민감도 인장 센서는 비교적 큰 변형을 요구하는 생체역학(biomechanics), 생리학(physiology), 신체 운동학(kinesiology) 등의 분야에 응용되고 있다.Stretchable electrode is applied to various fields such as artificial electronic skin, curved display, and tension sensor. Recently, as the potential applications of various tensile sensors, such as health rehabilitation treatment, personal health monitoring, structural defect monitoring, and sports player performance monitoring, have been re-examined, studies on flexible, flexible, and tensile-sensitive tensile sensors have been actively conducted. . In particular, high elasticity and high sensitivity tensile sensors have been applied to fields such as biomechanics, physiology, and kinesiology that require relatively large deformation.
신축성을 가지면서 전도성을 일정하게 유지해야 하는 일반적인 유연 전극과는 달리, 인장 센서로 활용되기 위해서는 높은 신축성을 가지면서 동시에 인장에 따른 연속적인 전기적 특성 변화를 가져야 한다. 하지만 기 개발된 인장 센서의 경우, 굽힘과 인장 응력이 공존하는 비평면 구조(특히 인체)에 응용되기 어려움이 있다. 이를 해결하기 위해, 전도성 물질의 종류를 바꾸는 방법에 연구되어 왔으나, 단순히 전도성 물질의 변화만으로는 재료적인 한계로 인해 신축성과 민감도 두 가지 중요 요소를 동시에 구현하지 못하는 문제가 있었다.Unlike a general flexible electrode that has a stretch and must maintain a constant conductivity, in order to be used as a tension sensor, it must have a high stretch and have a continuous change in electrical properties due to tension. However, in the case of a previously developed tensile sensor, it is difficult to be applied to a non-planar structure (especially the human body) in which bending and tensile stress coexist. In order to solve this, a method of changing the type of the conductive material has been studied, but there is a problem in that it is not possible to simultaneously implement two important factors such as elasticity and sensitivity due to material limitations only by changing the conductive material.
따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 실시예에 따르면, 관절의 움직임에 따른 정보수집이 필요한 스포츠에서의 동작분석을 위한 스트레인 센서를 제공하는데 그 목적이 있다.
