In article number 1802359 , Takao Someya and co‐workers demonstrate ultraflexible near‐infrared organic photodetectors that simultaneously exhibit high‐speed light responsivity and the smallest bending radius ( r = 3 μm). Stable operation is secured under severe mechanical deformation, even when the device is attached to a curved and/or folded part of the human skin. Using this ultrathin photodetector, a fingerprint‐conformal photoplethysmogram sensor is demonstrated.
