Through the developed internet of inspectionassessment device the digital twin model of specific implant structure can be constructed by using daily collected data besides assessing the osseointegration status of varied stages. The built model may trace the subject’s osseointegration changing. The internet of inspection device can also be applied for the health inspection of tapsdrills. Two types of inspection mechanism, electro-magneticvibro-acoustic, have been implemented in the device. The stability of structure is assessed through the computed frequency response function.

NCREE has originally developed 5D digital space—on the basis of 3D city modelsconnections of different kinds of sensors around the world— is an online to offline virtual space with a combination of rising 5G technology advantages. Collectingreorganizing various 3D cartographic data with Building Information Modeling (BIM), satellite imagery, UAV 3D modeling, LiDar point cloud data, etc., can increase the diversity of the buildinglandscape. 5D+5G smart city platform would accelerate the 5D smart city to become the digital twin of a real city.
