/PDMS Polymer cantilever structure integrated with a Graphene/PDMS composite sensor for detecting contractile force of cardiomyocyte and manufacturing of the same

摘要

The present invention relates to a polymer cantilever structure integrated with a graphene / PDMS composite sensor capable of precisely measuring the contractile force of cardiac muscle cells in real time, and a method of manufacturing the same. The polymer cantilever structure of the present invention comprises a cantilever A body portion 100 of a PDMS material having a plurality of microscopic groove patterns 111 formed integrally with the cantilever 110 and capable of culturing cardiomyocytes in a longitudinal direction on the cantilever 110; And a piezoresistive sensor 200 formed of a graphene / PDMS composite formed on one surface of the cantilever 110.
