CKGROUND: A wireless power transmission system is regarded as a practical way of solving power-shortage problems in multifunctional active capsule endoscopes.METHODS: The uniformity of magnetic flux density, frequency stability and orientation stability are used to evaluate power transmission stability, taking into consideration size and safety constraints. Magnetic field safety and temperature rise are also considered. Test benches are designed to measure the relevent parameters. Finally, a mathematical programming model in which these constraints are considered is proposed to improve transmission efficiency. To verify the feasibility of the proposed method, various systems for a wireless active capsule endoscope are designed and evaluated.RESULTS: The optimal power transmission system has the capability to supply continuously at least 500 mW of power with a transmission efficiency of 4.08%.CONCLUSIONS: The example validates the feasibility of the proposed method. Introduction of novel designs enables further improvement of this method.
