Introduction

Wireless power transfers have been extensively investigated for a variety of applications, including electric vehicle charging, smartphone charging, RFID devices, implanted device powering, and much more. Near field and far field power transfer applications are two types of wireless power transfer applications. Inductive resonance frequency coupling (IRFC), ultrasonic energy transfer, and near-field capacitive coupling are three forms of near-field approaches (NCC) [1]. Other researchers had previously performed a comparison of the properties of each type of wireless power transfer.

According to the comparisons done, each type of wireless power transfer has an advantage over the others. This justifies the fact that each type of WPT can be used depending on the biomedical implanted device's compatibility and requirements. The development of biomedical implants has resulted in the production of a variety of implantable devices to meet medical demands, including cardiovascular implantable devices, Cochlear implantable devices, neural implantable devices, retinal implantable devices, and more [2]. Each implantable device has its own set of parameters, particularly in terms of power characteristics, that allow it to function safely. Some implantable devices require a biosafety electrical power source to function properly. The implantable device's sealed battery can only provide energy for a limited amount of time [3]. The patient will be traumatised by the repeated battery replacement surgeries. Because of the constant reliance on electrical power sources, a wireless power transfer method is needed to overcome the restricted battery power source capability, which could save the patient from having to undergo surgery again to replace the battery of implants.

Conclusion

The goal of this research is to develop a new hybrid capacitive power transfer technology for biomedical implanted devices. According to this research, hybrid capacitive power transfer systems are a novel technology that could be used in biomedical implantable devices. The hybrid CPT techniques eliminated the return path active coupling plate to produce the whole current flow in the circuit, which was a solution to the bipolar CPT problem. The analysis revealed that the hybrid CPT system is more efficient than the bipolar system, which has a lower total output reactance value. The biomedical implantable device specification, however, limited all aspects, particularly size and biosafety.
