Abstract (in Japanese) (See Japanese page) 
(in English) The heartbeat of human iPS cell-derived cardiomyocytes was measured using a piezoresistive force sensor. The cells were seeded and beaten on a movable culture plate prepared by a silicon process, and the beat power was measured by sensing the movement of the plate with a piezoresistive cantilever. We investigated how the heartbeat cycle and intensity change depending on the temperature and compulsory extension length. These results are reported together with the experimental data. The higher the temperature of the medium, the shorter the beating cycle and the stronger the beating power. In addition, when cardiomyocytes were forcibly expanded, the beating power became stronger, which agrees with Frank-Starling’s heart law.
