CROSS-REFERENCE TO RELATED APPLICATION

This application is a national stage application, filed under 35 U.S.C. § 371, of International Patent Application No. PCT/KR2018/012692, filed on Oct. 25, 2018, which claims benefit of Korean application No. 10-2017-0141326, filed on Oct. 27, 2017, the contents of which are incorporated by reference.

TECHNICAL FIELD

The present invention relates to a core-shell nanowire, a method of forming the core-shell nanowire and a stretchable composite comprising the core-shell nanowire are provided.

BACKGROUND ART

The heart is one of the most important organs that are activated by propagation of electrical conduction through the His-Purkinje conduction system. Monitoring electrical activities of the heart helps to give a doctor an insight into the heart condition to diagnose specific diseases which is determined by a waveform of action potential in clinical care. In particular, local activation maps provide the information of the location of the impaired myocardium, and thus multiple spatially distributed recordings are demanded for interpreting comprehensive heart diseases. The conventional anatomical approach of the catheter electrode through the blood vessels makes electrical pacing at the desired site of the heart difficult. In order to solve these problems, an electrode with a net shape has been studied, but there is a problem that this electrode release highly toxic metal components.
