When a stretchable photodetector deforms, the effective light-detection location shifts across the skin surface, complicating the interpretation of spatially localized physiological signals. Herein, we report a periodic-buckling stretchable organic photodetector (OPD) that enables dual optical and strain sensing within a single device, allowing real-time estimation of changes in the effective detection position. The open-circuit voltage (\n                    <jats:italic toggle=\"yes\">V<\/jats:italic>\n                    <jats:sub>oc<\/jats:sub>\n                    ) depends solely on light intensity, whereas the short-circuit current (\n                    <jats:italic toggle=\"yes\">I<\/jats:italic>\n                    <jats:sub>sc<\/jats:sub>\n                    ) reflects both light intensity and variations in the active area, enabling geometric localization of the photodetection site. The OPD exhibits stable performance under applied strains of up to 60%, with variations in\n                    <jats:italic toggle=\"yes\">V<\/jats:italic>\n                    <jats:sub>oc<\/jats:sub>\n                    below 1.1% and a strain gauge factor of 0.44 derived from\n                    <jats:italic toggle=\"yes\">I<\/jats:italic>\n                    <jats:sub>sc<\/jats:sub>\n                    .
