Patch Type Electrocardiogram Sensor

#The present invention relates to a patch type electrocardiogram sensor which can be easily attached to body skin and measures a bio-signal.

#As an electrocardiogram (ECG), which is one type of typical bio-information, records action current generated when a myocardium contracts and relaxes due to a cardiac impulse, electrodes are attached to body skin, action current is measured according to myocardial contraction, and the data of the measured current is described in a graph.

#Specifically, an active potential occurring when a myocardium contracts and relaxes due to a cardiac impulse generates a current transmitted from the heart to the whole body, the current generates potential differences according to positions of portions of the body, and the potential differences can be detected and recorded by electrodes attached to the body skin.

#The description above and other objects, features and advantages of the present invention will become more apparent to those of ordinary skill in the art by describing exemplary embodiments thereof in detail with reference to the accompanying drawings, in which:

#FIG. 1 is a plan view of a structure of a patch type electrocardiogram (ECG) sensor according to one embodiment of the present invention;

#FIG. 2 is a cross-sectional view illustrating the patch type ECG sensor shown in FIG. 1;

#The present invention relates to a patch type electrocardiogram (ECG) sensor which is easily attached to a human body, improves convenience during an operation by simplifying the wiring structure, and measures a bio-signal.

#Here, an ECG represents a picture in which electrical activity of a heart is amplified and recorded, and such an ECG is used for measuring a heart condition or diagnosing the extent of heart damage.

#The present invention relates to a patch type ECG sensor including: a base layer having a pad form; a flexible printed circuit board (FPCB) layer formed on the base layer and having a film form; sensors formed on the FPCB layer and including a plurality of electrodes configured to acquire ECG signals and a plurality of electrode circuit parts which are constituted by circuit patterns and the ends thereof are individually connected to the plurality of electrodes; a main body formed on the FPCB layer and connected to the other ends of the plurality of electrode circuit parts to converge the plurality of electrode circuit parts; and an adhesive layer formed on the FPCB layer such that the plurality of electrodes are exposed and configured to attach the sensors to a human body, wherein a connection part configured to transmit the ECG signals to the outside is installed at and connected to the main body, and the main body and the connection part are connected by a single wire.
