To deal with the power shortage of the implantable radio-telemetry system for animal physiological parameters dictation, a wireless power transmission system based on electromagnetic induction is proposed. The parameters of the couple coils are optimized considering the safety and stability of this power transmission, transmitting coil of rectangle section solenoid and three-dimensional receiving coil are selected. Experiments show that at least 150mW power could pick up on the load in a volume of Φ10.5 mm×11 mm with a transmission efficiency of 2.56%. Vivisection experiments verified the feasibility of the integrated radio-telemetry system based on this power supply technology.

Power shortage is the bottleneck for the wide application of gastrointestinal (GI) robot. Owing to the limited volume and free change of orientation of the receiving set in GI trace, the optimal of receiving set is the key point to promote the transmission efficiency of wireless power transmission system. A new type of receiving set, similar to the winding of three-phase asynchronous motor, is presented and compared with the original three-dimensional orthogonal coil. Considering the given volume and the space utilization ratio, the three-phase and the three-orthogonal ones are the parameters which are optimized and compared. Both the transmission efficiency and stability are analyzed and verified by in vitro experiments. Animal experiments show that the new one could provide at least 420 mW power in volume of [Formula: see text] with a uniformity of 78.3% for the GI robot.

Power Transmission System

This paper presents the development of a medium-power wireless power transmission system for use in robotics and other applications. The presented system can be used to power devices or charge batteries. The system is based on the principle of inductive power transmission. A feature of the system is the use of a resonant self-oscillator, for which the transmitting LC circuit of the system is a frequency setting. The use of identical receiving and transmitting resonant circuits makes it possible to refuse additional frequency control devices in the receiving part of the system. The presented circuitry solution of the wireless power transmission system ensures operation in the resonance mode in the receiving and transmitting circuits, where the receiving and transmitting coils are at various positions relative each other, while not requiring a dedicated monitoring and control system for this. Experimental verification of the proposed solution was carried out on a prototype of a system with shell elements, shielding from magnetic fields, while the maximum level of efficiency of the system without an output stabilizer in the receiving part was 80.41%, with a transmitted power of 131.5 W, at a transmission distance of 15 mm. The dependency curves of the efficiency and the transmitted power were obtained for three distances of energy transfer — 0 mm, 15 mm and 30 mm. With distances between the coils up to 30 mm, the efficiency of the system is above 70% with a transmitted power of more than 55 W. Key words Wireless charging system, wireless power transmission, resonant oscillator, wireless power transmission efficiency.
