Abstract: Disclosed is a spike spectrum output-type pressure sensor including an electrolyte and a method of manufacturing the same. The pressure includes a first electrode, a pressure sensing unit positioned on the first electrode and including a pattern including an electrolyte, a spacer positioned on the first electrode and configured to partially or fully surround the pressure sensing unit, and a second electrode positioned on the spacer and on the pressure sensing unit and spaced apart from the pressure sensing unit. The pressure sensor of the present invention can provide reliable pressure sensing results even in an environment where noise may occur due to stable signal transmission of a spike spectrum, which is a kind of frequency-based signal.

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.
