Abstract :
This paper describes a novel keyless entry system, in which the touching signal is transmitted through the human body as a conductor instead of via radio wave. The coding key is generated using the M-sequence. We developed a prototype of the smart touch sensor in which the intelligence was realized by software stored in a PIC16F84A microchip. The PIC processors produces a programmable on-off signal in the sampling interval of 0.2/spl mu/s. In the processor the coded key signal is produced and transmitted very quickly.
