Abstract Visual and tactile information are the key intuitive perceptions in sensory systems, and the synchronized detection of these two sensory modalities can enhance accuracy of object recognition by providing complementary information between them. Herein, multimodal integration of flexible, high‐resolution X‐ray detectors with a synchronous mapping of tactile pressure distributions for visualizing internal structures and morphologies of an object simultaneously is reported. As a visual‐inspection method, perovskite materials that convert X‐rays into charge carriers directly are synthesized. By incorporating pressure‐sensitive air‐dielectric transistors in the perovskite components, X‐ray detectors with dual modalities (i.e., vision and touch) are attained as an active‐matrix platform for digital visuotactile examinations. Also, in vivo X‐ray imaging and pressure sensing are demonstrated using a live rat. This multiplexed platform has high spatial resolution and good flexibility, thereby providing highly accurate inspection and diagnoses even for the distorted images of nonplanar objects.
