Engineers have demonstrated an electronic device to closely monitor beating heart cells or cardiomyocytes without affecting their behaviour. Inside each of us beats a life-sustaining heart. Unfortunately the organ is not always perfect and sometimes goes wrong. One way or another research on the heart is fundamentally important to us all. When researchers study cardiomyocytes in action they culture them on hard petri dishes and attach rigid sensor probes. These impede the cells' natural tendency to move as the sample beats so observations do not reflect reality well said one of the researchers Sunghoon Lee from the University of Tokyo
