Abstract. wireless power transfer (wpt) systems have become increasingly suitable solutions for the electrical powering of advanced multifunctional micro electronic devices such as those found in current biomedical implants. the design and implementation of high power transfer efficiency wpt systems are, however, challenging.

Figure 1 From High Efficiency Wireless Power Transfer For Biomedical Various near field to far field wireless power transfer methods have been proposed for imds, such as inductive wpt, far field rf wpt, and apt. however, as the size of the implant shrinks, the efficiency of inductive and rf power transfer decreases significantly due to the relatively large wavelength and attenuation at high frequencies . The standard limit for 1 g tissue is 1.6 w kg for an input power of 1 w; thus, the proposed wpt system is suitable for the wireless powering of the biomedical implants using 0.915 and 2.45 ghz. The standard limit for 1 g tissue is 1.6 w kg for an input power of 1 w; thus, the proposed wpt system is suitable for the wireless powering of the biomedical implants using 0.915 and 2.45 ghz frequency bands. figure 17. specific absorption rate of the wpt system at ( a) 0.915 ghz, and ( b) 2.45 ghz. table. The home cage unit includes a transmitter coil array and segmented multi coil resonators. this hybrid model is important to achieve high power transfer efficiency and high power. the oscillating system frequency is 13.56 mhz. the result showed that for 0 and 20 cm distances, the power transfer efficiencies are 50% and 12%, respectively.
