An innovative Memristor-based Wireless Power Transfer for NFC Security

In the traditional Wireless Power Transfer (WPT) circuits the inverters are used to produce an oscillation for the transmitter coils. This includes intrinsic energy dissipation sources due to the use of switches, necessitating the need for an extra control circuit to ensure proper switching time. Those circuits also have limited encryption capabilities. In order to overcome these challenges, we have proposed an innovative near-field power and chaos transmission method based on the memristor and applied it to Near Field Communication (NFC) security. We created Chua circuits capable of chaotic self-oscillation, avoiding the use of extra switches. Both circuits exhibit synchronised chaotic behaviour depending on parameters and equivalent emulator for memristors, which could be used to generate a distinct cryptography.
