Comprehensive Summary: Electrochemical sensing faces huge challenges in characterizing the transient release of biochemical molecules from deformed cells, due to the severely mechanical mismatch between rigid electrodes and soft cells. In recent years, the emergence of stretchable electrochemical sensors has made a breakthrough by complying with the deformation of living cells and simultaneous monitoring of mechanically evoked biochemical signals. This review first summarizes two fundamental strategies for the fabrication of stretchable electrodes from the points of structure and material. Next, recent progresses in construction of functionalized interface to improve the performance of stretchable electrochemical sensors are presented. Then, the application of stretchable electrochemical sensors in real‐time monitoring of biomolecules released by mechanically sensitive cells is introduced. Finally, some perspectives and challenges of stretchable electrochemical sensors regarding cell detection are discussed. What is the favorite and original chemistry developed in your research group? The design and construction of electrochemical sensing platform for real‐time monitoring of life activities. What is the most important personality for scientific research?
