This paper presents the realization of the miniature and flexible defected ground structure-based wireless power transfer (WPT) system suitable for biomedical applications and the evaluation of the bending effect on the overall system performance. Firstly, the compact resonator of 22-by-22 sq. mm area is designed with an octagon spiral defect shape. Secondly, the WPT realization is achieved with two identical resonators distanced by a 20 mm transmission range. Eventually, the system performance with unchanged and bent transmitters is verified. The WPT system showed a power transfer efficiency of 67% with unchanged and 61 % with bent transmitting resonator.
