Mission Statement

Background
Shrinking technologies today allow new applications especially in the medical field. Radio Frequency inductive links are becoming extensively used for telemetry and wireless powering of implanted devices such as biomedical sensors and RFID implants. This power or even data transfer only is possible when the transfereing end and receiving end are matched and a sufficently large current is drawn through the sending coil. Wireless power transfer is an underlying requirement to embedded devices in your body because we would not want to reach the device neither by cable, nor directly because it would require regular chirugical operations to retrieve the device to recharge it and then re-implant it. Thus for the wireless power transfer, we will be using predefined frequencies in the range of 6.7MHz to 13.5MHz, which are not dangerous to our body structure.

Aims
• To find the most appropriate transfer circuit.
• To draw a maximum current through the TX coil to induce a large electromagnetic force.
• To match at best the TX end to the RX end so that the power transfer can then be maximised.

Interim Targets.
Experience in RF engineering and more specifically in matching circuits will be necessary for the project. This project should allow me to gain a good understanding of the electromagnetic fields and hopefully knowledge from information sources will enable me to produce by week 10, an interim report, which will clarify my aims for the project and help me organise my time dedicated to the project for the second semester.
