The outputs of a microhotplate gas sensor array (16 sensors) are encoded as a spike train and transmitted wireless to a mobile phone for gas recognition. The generated spike train is insensitive to changes in gas concentration. The properties of this device (compactness, low power consumption) make it suitable for embedded gas sensor applications (smellphone). This study pioneers the translation of neurophysiological findings into hardware for the processing of electronic noses.<br />Reference: Chen, Ng, Bermak, Law and Martinez (2010) Spike latency coding in a biologically inspired micro-electronic nose IEEE Trans.
