RFCPUs on glass and plastic substrates fabricated by TFT transfer technology

On the basis of the fabrication of a CPU on glass as a digital circuit presented in B. Lee et al. (2003) and T. Ikeda et al. (2004), as well as the fabrication of a flexible CPU using a TFT transfer technology presented in T. Takayama et al. (2004), we have succeeded in the development of the world's first flexible RFCPUs (8bit, passive type) by adding to the CPU an antenna, an analog circuit, an encryption function and an RFID function, which operate using an RF signal with a frequency of 13.56MHz
