3D Printed Electromyography Sensing Systems

Electromyography (EMG) has been widely used in robotics and biomedical applications for sensing and diagnostic purposes. Because of the complex shape of human limbs and the uneven and flexible surface of the human skin, EMG sensing often faces the challenge of stable signal detection. As manufacturing technology advances, additive manufacturing has shown its potential to improve the existing EMG sensing system further. 3D printing technologies offer the advantage of custom fabrication to fit the designated locations of EMG detection. 3D printing also provides flexible and stretchable features, which allow for a comfortable user experience. This paper presents the recent development of novel 3D‐printed EMG sensing systems. The process of EMG signal detection is compared with the standard system. The corresponding applications with 3D‐printed sensing systems in different fields of study are also discussed. Finally, by reviewing the state‐of‐the‐art technology, the future of 3D printing in EMG sensing and the challenges facing the field are discussed.
