Abstract :
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
