- Wireless thin film transistor (TFT) structure has been studied to apply to various flexible or wearable devices. For employing micro antenna structure to TFT, the magnetic core (MC) is added to the micro antenna structure to enhance the delivered wireless power and signal due to the decrease of the power efficiency as the scale down of antenna size. The MC is consisted of ZnO nano-wires and Ni, a ferromagnetic material, which is coated on the vertical ZnO nano-wires. Due to the increase of self-resonance frequency with decreasing antenna size, we choose and fabricated a-IGZO TFT, which can have a higher mobility than a-Si TFT. The result enhances the wireless transferred power efficiency of the TFT with micro antenna structure. © 2014 IEEE.
