An international team, including the University of Tokyo, developed a sensor inspired by the fish lateral line that measures pulse in lab-grown 3D heart tissue (cardiac organoids). The device, described as a biomechanical well plate, uses a multiwell format designed to quantify beating dynamics. This kind of measurement platform can accelerate early-stage cardiac biology workflows by standardizing how researchers evaluate organoid function and response to interventions. For drug discovery and tissue-model validation, consistent, noninvasive readouts are a persistent bottleneck. The development matters because it provides a practical instrumentation approach for organoid physiology studies, potentially improving throughput and reproducibility compared with more traditional measurement setups.
