Highly sensitive three-dimensional scanning triboelectric sensor for digital twin applications

Digital twin benefits for product designing, simulating, and troubleshooting. To obtain a more realistic digital model, it is crucial to accurately collect point could data in the complex environment affected by light, sound, and electromagnetic fields. In this paper, a three-dimensional (3D) scanning system is proposed to achieve distinguishing output and almost damage-free point cloud collection to the surface of objects. Thanks to the linearity between voltage signal and sliding displacement of sliding triboelectric nanogenerator (S-TENG), a self powered point cloud collecting probe has been designed. More importantly, S-TENG probe generates high voltage with little friction force making it almost no damage to the contact surface of the sample object while scanning. To enormously improve the accuracy of the whole system, a productive post-processing system has been proposed to recognize and compensate for the noise and baseline drift errors caused by the surrounding environment. This system vigorously promotes the development of digital twin technology, contributing to intelligent manufacture, intelligent medical care, and cultural relics protection.
