Advances in Wearable Bioimaging

Abstract

ABSTRACT The development of wearable bioimaging platforms has accelerated in the era of precision medicine, addressing the limitations of conventional, facility‐based systems, which can be costly and difficult to access. In this review, we first outline the operating principles of major imaging modalities, with an emphasis on target tissues and factors that contribute to image quality. Next, we survey advances in miniaturizing these modalities into wearable devices, from electrical impedance tomography belts to flexible ultrasound and photoacoustic patches, highlighting materials selection and fabrication strategies that enhance image quality, skin adhesion, and functional integration. Lastly, we discuss outstanding technical and translational challenges that must be addressed to realize the full potential of these platforms, including safety and long‐term use. With sustained research and responsible commercialization, these wearable devices could reshape continuous physiological monitoring and enable more proactive, preventive health management.
