Abstract: Proposed are a sensor for simultaneously measuring electrocardiogram and mechanocardiogram and a method of manufacturing the same. The sensor for simultaneously measuring electrocardiogram and mechanocardiogram includes a base mat including nanofibers including a polymer, and having a porous structure, and a conductive pattern portion impregnated into the base mat to a predetermined depth and including a first pattern for measuring the electrocardiogram and a second pattern for measuring the mechanocardiogram. Each of the first pattern and the second pattern includes nanofibers including the polymer, and a conductor located between the nanofibers. The sensor for simultaneously measuring electrocardiogram and mechanocardiogram has excellent mechanical and electrical stability against stretching. Thus, the long-term use of the sensor as an implantable electrode enables stable simultaneous measurement of electrocardiogram and mechanocardiogram.
