Video capsule endoscopy is an innovative technique that enables the clinical evaluation of the Gastro-Intestinal tract through a non-invasive approach. Two primary types of video capsules are available: passive and active. Magnetically Driven Video Capsule Endoscopy, is an advanced diagnostic active video capsule that revolutionizes the visualization of the Gastro-Intestinal tract. This method employs an external magnetic field to activate the capsule and facilitate the observation of the gastrointestinal tract. This article will provide a comprehensive review of magnetically driven video capsules, including a focus on external navigation systems for capsule locomotion. Experimental investigations, containing technical and/or clinical tests, will be described. The goal of this review is to emphasize the effectiveness of magnetic fields in propelling video capsules. Also, the efficacy of this device in terms of mobility and disease detection will be assessed based on technical and clinical trial outcomes. The results showed that the mechanical features, such as rotational speed, movement speed, amount of capsule rotation, velocity, frequency and amplitude of vibration of capsule were measured through the technical tests. Experimental results indicate the successful use of the magnetic field to drive and rotate the capsule.
