The Non-Invasive Contractility Evaluation (NICE) platform is essentially a smart petri dish designed specifically for heart cells. While traditional petri dishes just provide a flat surface for cells to grow, the NICE platform contains special materials that can measure how strongly heart cells are beating without disturbing them.

Think of it like a fitness tracker for heart cells. When heart cells contract (beat), they create tiny mechanical movements. The NICE platform has a special material (piezoelectric-PDMS or PE-PDMS) that converts these tiny mechanical movements into electrical signals, similar to how pressure on a touchscreen creates an electrical response. These signals are then measured to tell researchers exactly how strongly the heart cells are contracting without needing to constantly observe them under a microscope.

This technology allows scientists to test how heart cells from different people respond to various drugs or treatments, potentially leading to more personalized heart treatments.
