“…Besides, the measurement of pheromone elicited cellular responses, the communication system design presented here has also been successfully used to demonstrate the concept of infochemical-based ratiometric communication. Using binary mixtures of plant compounds, ethyl acetate, and isoamyl alcohol, information was ratiometrically encoded and released into the environment, then successfully detected and recovered with an array of polymer-coated SAW resonator sensors using steady-state sensor outputs [23]. The chemoreceiver module can facilitate high-resolution real-time measurements as well for dynamic feature extraction and data analysis using a neuromorpic model.…”

We describe here the design and implementation of a novel biomimetic infochemical communication system that employs airborne molecules alone to communicate over space and time. The system involves the design and fabrication of a microsystem capable of producing and releasing a precise mix of biosynthetic compounds and a sensor system capable of detecting and decoding the ratiometrically encoded chemical information.The research inspired by biology has been based upon the biosynthetic pathways of infochemical production and information processing within the insect world. In this novel approach, the functional equivalents of the nanoscale biological machinery are implemented by combining the latest advances and convergence of expertise in the fields of biochemistry, molecular biology, neuroscience, micro-and nanofabrication, materials science, and smart sensor and microcircuit design. The biomimetic system comprises a micromachined bio-reactor mimicking the sex gland of the female insect that releases a blend of pheromones in precisely controlled ratios, together with a cell-based biosensor system, mimicking the antennae of the male insect. The signals from the biosensors are classified and ratios decoded using a field-programmable gate array implementation of a neuromorphic model of the antenna lobe of the insect.We believe that this novel, smart infochemical communication system, inspired by the insect's behavior, could eventually be implemented in VLSI technology at low cost and low power with possible application in the fields of automatic identification and data capturing, product labeling, search and rescue, environmental monitoring, and pest control.

“…The basic configuration of the communication system involves a microsystem, called the chemoemitter module , which is capable of producing and releasing a precise mixture of ratiometric biosynthetic pheromone compounds, and a sensor system, called the chemoreceiver module , which is capable of detecting these biosynthetic ligands and decoding the ratiometrically encoded information [ 11 , 14 , 15 , 16 ]. A prototype of the modular infochemical communication system has been constructed and assembled, as shown in Figure 2 a.…”

Biosynthetic infochemical communication is an emerging scientific field employing molecular compounds for information transmission, labelling, and biochemical interfacing; having potential application in diverse areas ranging from pest management to group coordination of swarming robots. Our communication system comprises a chemoemitter module that encodes information by producing volatile pheromone components and a chemoreceiver module that decodes the transmitted ratiometric information via polymer-coated piezoelectric Surface Acoustic Wave Resonator (SAWR) sensors. The inspiration for such a system is based on the pheromone-based communication between insects. Ten features are extracted from the SAWR sensor response and analysed using multi-variate classification techniques, i.e., Linear Discriminant Analysis (LDA), Probabilistic Neural Network (PNN), and Multilayer Perception Neural Network (MLPNN) methods, and an optimal feature subset is identified. A combination of steady state and transient features of the sensor signals showed superior performances with LDA and MLPNN. Although MLPNN gave excellent results reaching 100% recognition rate at 400 s, over all time stations PNN gave the best performance based on an expanded data-set with adjacent neighbours. In this case, 100% of the pheromone mixtures were successfully identified just 200 s after they were first injected into the wind tunnel. We believe that this approach can be used for future chemical communication employing simple mixtures of airborne molecules.
