Optimisation Verification for a Millimetre-Scale Vibro-Impact Capsule System

A self-propelled capsule endoscope moving inside patient's gut is a promising means of minimising patient's painful investigation and improve the diagnostic efficiency. This paper presents the study of a millimetre-scale capsule prototype that can be propelled by external magnetic field via vibration and impact, from both mathematical modelling and experiment, showing a high progression speed up to 5.3 mm/s. Good agreement between numerical simulation and experimental investigation demonstrates the feasibility of the proposed driving method for small-bowel capsule endoscopy.
