Background Prosthesis is a wearable device that intends to provide the functionality and/or appearance of a missing body part. In the case of trans‐radial prostheses, the wearer or the trans‐radial amputee is fitted with an artificial wrist and a hand that is either mechanically or electro‐mechanically operated. Main aim is to enable the wearer to perform activities of daily living with minimal external assistance. Methods In this review paper, hardware systems of state‐of‐the‐art trans‐radial prostheses have been briefly discussed. Focus is to provide an insight on the latest technologies employed in development of its mechanical systems: terminal devices, artificial wrist joints, and body attachments. In that context, latest hardware designs on terminal devices for grasping motion are presented as it is the primary function of trans‐radial prostheses. Hardware designs of prosthetic wrists and body attachments are also reviewed. Finally, latest trends and future directions on design of trans‐radial prostheses are explored and presented. Conclusions Size, shape, weight, durability, appearance, and functionality are the key factors that need to be considered when developing a trans‐radial prosthesis. Moreover, the current developments are moving closer to a human upper limb. However, the availability of these devices is minimum due to high‐tech involved and the high cost, which necessitates further development trans‐radial prostheses.
