Flexible near-infrared imaging device with variable monitoring area and depth and preparation method thereof

Abstract

The invention provides a flexible near-infrared imaging device with variable monitoring area and depth and a preparation method thereof, the flexible near-infrared imaging device is suitable for being attached to the outside of human skin to monitor tumor tissues in human tissues, and the flexible near-infrared imaging device comprises a conductive part which comprises a plurality of insulating layers; each metal layer is arranged between two adjacent insulating layers and comprises a plurality of bent metal wires wrapped by the insulating layers and a plurality of groups of bonding pads which are respectively connected with the bent metal wires in series and are exposed out of the insulating layers; a plurality of light emitting parts electrically connected with the bonding pad and configured to emit a first light beam to the tumor tissue; the plurality of photoelectric detection parts are electrically connected with the bonding pad and are configured to receive the second light beam which is absorbed by the tumor tissue and then reflected back; and the packaging layer is made of shape memory polymer and supports the conductive part, so that the bent metal wire is pulled to extend or contract under the condition that the packaging layer is deformed, and the distance between the light-emitting part and the photoelectric detection part is increased or decreased.

Description

technical field [0001] The invention relates to the field of semiconductor devices, in particular to a flexible near-infrared imaging device with variable monitoring area and depth and a preparation method thereof. Background technique [0002] In recent years, the morbidity and mortality of malignant tumors are on the rise, posing a serious threat to people's lives and health. At present, among the various existing technologies that can detect and diagnose human tumors, such as: X-ray imaging, MRI imaging, ultrasound imaging, etc., due to their large size and expensive equipment, they are not suitable for patient self-examination. , and can not meet the needs of long-term monitoring. In addition, imaging technologies such as X-ray and ultrasound may cause unpredictable damage to the human body, making daily detection more difficult to achieve. Therefore, the research on malignant tumor monitoring devices has strong social significance. SUMMARY OF THE INVENTION [0003]...
