Abstract

Abstract: Precise multi-axis operation is essentially required in orthodontics for tooth movement. Despite the development of flexible multi-dimensional force sensors that have effectively perceived multi-dimensional forces, they still face the challenge of simultaneously 3D force and moment in a single flexible force sensor. Six-dimensional force perception can successfully operate objects that critically rely on directional tracking and accurate monitoring of complex multi-axis stimuli. To realize the integration of sensing units with the perception of six-dimensional force under even a soft touch, we design a flexible six-dimensional force sensor with tenon-and-mortise interlocking structures inspired by traditional Chinese ancient architecture. This unique structure enables conjunction of deformation, which can be studied and decoded by Deep Neural Networks (DNN) with six-dimensional force, including forces and rotating moments in the x, y, and z directions. This soft sensor with minimal size (7 × 7 × 7 mm 3 ) and high detection accuracy (the DNN error is below 10 −4 ) can be used in orthodontic treatment for precise correction with a full collection of orthodontic force. This unique flexible six-dimensional force sensor provides a new strategy for the design of multi-dimensional force sensors, paving the way for the development of intelligent robotics, interactive human-machine interfacing, and advanced prosthetics. Graphical Abstract: Inspired by the tenon and mortise construction of ancient Chinese architecture, this work develops a flexible six-dimensional force sensor with the ability to sense three-dimensional force and three-dimensional moment. The sensor signal can be decoded by DNN to output six-dimensional forces, thus providing orthodontic force information for orthodontics and helping dentists to improve treatment plans. ga1 Highlights: A flexible tactile sensor is proposed to perceive the six-dimensional force through the tenon-and-mortise structure. Multidimensional sensing information can be decoded and converted into six-dimensional force by DNN. The flexible six-dimensional force sensor for orthodontic demonstrates its effectiveness as a treatment aid.
