Metamaterial Super-Lens For Improving Of Wireless Power Transmission To A Tear Glucose Sensor

Abstract
Tear glucose sensor embedded in a contact-lenscan be charged up using wireless power transmission with inductive coupling technique. In this paper, the simulation is performed to study power transmission improvement using metamaterial as a super-lens. Metamaterial or left-handed side material acts as a poweramplifier. It is placed between transmitter and receiver coils. The magnetic field intensity is employed as a power measure. The previous method without the super-lens provides around 50 A/m received magnetic field intensity at the resonant frequency of 819 KHz. After installing the 10 mm thick slab of super-lens in the center between transmitter and receiver coils, the received field intensity increases to 480 A/m. Wi-Fi frequencies of 2.45 GHz and 5.80 GHz are simulated for comparison. The dependence of the magnetic field intensity on the super-lens thickness is also investigated. All results indicate potential of the metamaterial technique in power transmission enhancement for the tear glucose contact-lens sensor.
