Zusammenfassung:The present invention relates to a sensor (100) using characteristics that impedance of a carbon micro-coil (131) forming a sensing sheet (130) of the sensor (100) changes as an object approaches the sensing sheet (130) of the sensor (100), is separated from the sensing sheet (130), comes in contact with the sensing sheet (130), or applies weight and to a method for manufacturing the same. The sensor (100) comprises: an electrode unit (110); the sensing sheet (130) which functions as an impedance device with respect to alternating current applied to the electrode unit (110); a substrate (120) having the electrode unit (110); and an attachment layer (140) which is located between the sensing sheet (130) and the substrate (120) having the electrode unit (110) and has a function of attaching the sensing sheet (130) and the substrate (120) to each other. Provided is the sensor having the sensing sheet (130) comprising the carbon micro-coil (131). 본 발명은, 물체가 센서(100)의 감지시트(130)에 접근, 이격, 접촉 또는 하중작용함에 따라 센서(100)의 감지시트(130)를 구성하는 탄소마이크로코일(carbon micro coil)(131)의 임피던스가 변화하는 특성을 이용한 센서(100) 및 그 제조방법에 관한 것으로, 전극부(110), 상기 전극부(110)에 인가되는 교류에 대하여 임피던스 소자로서 기능하는 감지시트(130), 상기 전극부(110)가 형성되어 있는 기판(120), 상기 감지시트(130)와 상기 전극부(110)가 형성되어 있는 상기 기판(120) 사이에 위치하여, 상기 감지시트(130)와 상기 기판(120)을 상호 접착하는 기능을 구비하는 접착층(140)을 포함하여 이루어지고, 상기 감지시트(130)는 탄소마이크로코일(carbon micro coil)(131)을 포함하는 것을 특징으로 하는 센서(100)를 제공한다.
