Abstract
Implantable devices require miniaturization, stability, and long-term operation characteristics for monitoring and stimulation within the tissue. Generally, batteries have been used in the implantable device for long-term operation ability. However, implantable devices using batteries have limitations such as large size, short lifetime, and periodical replacement surgery. Therefore, wireless power transfer (WPT) system has been reported as alternative method to long-term operation of implantable devices. Recently, WPT systems based on metasurfaces, that exhibit exotic electromagnetic (EM) characteristics with sub-wavelength thickness, were introduced in bioelectronics to improve the efficiency and to reduce the geometrical dimension of WPT system.
