Abstract

The invention discloses an in-vivo heart organ chip and method. The in-vivo heart organ chip comprises a substrate device and a culture solution perfusion device, wherein a PDMS thin film is arranged on a surface of the substrate device, and the culture solution perfusion device is arranged at a top of the PDMS thin film to simulate blood flowing condition; the substrate device comprises a substrate, a PDMS mold is arranged on a surface of the substrate, and the PDMS mold is provided with a micro gas channel; the PDMS thin film comprises a suspended thin film, and the suspended thin film is provided with a strain sensing part, an induction electrode and a stimulating electrode.

Description

technical field [0001] The invention belongs to the technical fields of micro-electromechanical engineering and biomedicine, and in particular relates to an in-vivo heart organ chip and a method thereof. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Globally, cardiac dysfunction-induced cardiovascular death accounts for 33% of the total death toll, ranking first in the global death toll. [0004] At present, the existing micro-nano sensor devices for myocardial contractility (or stress) detection have the following types: [0005] The electrical impedance method (Electrical impedance) was proposed by Gievar et al. In this method, cardiomyocytes are planted on the interdigitated microelectrode array chip, and the distance between the bottom of the cell and the upper surface of the electrode is changed during the beating process of the cells, ther...
