Human multisensory neurons integrate multiple sensory informationobtained from the environment for interpretation of an event. Inspired bybiological multisensory integration/multiplexing behavior, an artificial multimodalintegration system emulating the perception of discomfort based on theintegration of multiple sensory signals is presented. The system utilizes asensory ring oscillator that integrates thermosensory and hygrosensory signals fromreceptors into voltage pulses whose amplitude and frequency reflect the twosensory signals. Subsequently, a synaptic transistor translates voltage pulsesinto a postsynaptic current, which exhibits a high correlation with thecalculated humidex. Finally, the feasibility of the artificial multimodalintegration system is successfully demonstrated using light-emitting diodediscomfort indicators, suggesting that the proposed system can act as afoundation for future studies pertaining to neuromorphic perception and complexneurorobotics. |
