    Odor-shift keying, a data modulation technique that encodes digital data by varying odor presentation, was proposed in this paper. A multi-channel olfactory display was used as modulator to release multiple odors whose blending ratio representing different digital data. On the demodulator side, an odor sensing system is used to measure the released smells, revert them into electrical form which is then decoded into the original data by using digital signal processing. The proposed technique can enhance data transfer rate of the communication through odor as carrier. A preliminary experiment was conducted to validate the possibility of the concept of varying the presented odors to represent different binary data. Finally, a string was practically modulated and transmitted by using the proposed technique. The demodulation process can be performed successfully and the data transfer rate was doubled from the previous work.

    This study proposed a novel data modulation technique for digital communication by using a concentration of odor molecules. The information is encapsulated in an odor with controlled concentration levels in accordance with the binary representation of the message by using an olfactory display. The released odor is then measured by an odor sensing system where it is converted into electrical form that can be demodulated into the original data by using a digital filter and decision decoder. The experiments of sending a message by mean of odor in the UART format were performed to evaluate the possibility of the proposed molecular communication approach. The results reveal that the shape of signals detected by the odor sensor is associated with the information in the message, which confirms the reliability of data communication using this method.
