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