PROJECT TITLE :

Wireless power transmission in human tissue for nerve stimulation

ABSTRACT:

Wireless power transmission in human tissue using microwave techniques has nice potential for various biomedical applications. Characterisation and optimisation of those techniques using in vivo performance measurements are complicated and time consuming. This study investigates the electromagnetic performance of microwave wireless power transmission at 2.45 GHz. For this purpose, a computational model of a measurement system is proposed and used to characterise and optimise a microwave wireless power transmission technique capable of delivering microwave power to a localised space in the human tissue. This technique includes an implanted miniature encased microstrip ring disk antenna and an external microstrip patch antenna operating at two.45 GHz. The results show that the microwave technique will be optimised by matching the radiation directions and polarisations of the antennas and by inserting a dielectric layer between the human tissue and also the external antenna. It is demonstrated that the optimised microwave technique will deliver an electrical stimulus that may be used for biomedical applications like nerve regeneration with a particular absorption rate that satisfies the IEEE Standards.
