CARDIAC PLATFORM FOR ELECTRICAL RECORDING OF ELECTROPHYSIOLOGY AND CONTRACTILITY OF CARDIAC TISSUES

摘要

Disclosed here is a cardiac platform, comprising a substrate layer comprising a substrate and a plurality of micro-strain gauges and a plurality of microelectrodes disposed on the substrate, a patterned layer disposed on the substrate layer which insulates the micro-strain gauges and exposes the microelectrodes, and a plurality of pillars disposed on the patterned layer. Also disclosed is a method for detecting electrophysiology and contractility of cardiac cells or tissues, comprising providing a cardiac platform that further comprises cardiac cells or tissues disposed on the pillars, and detecting electrophysiology of the cardiac cells or tissues using the microelectrodes and detecting contraction force of the cardiac cells or tissues using the micro-strain gauges.
