Abstract
A portable communication device includes one or more sensors, a pair of electrodes associated with each sensor, and a processing circuit configured to apply a bias supply voltage to the pair of electrodes and to process output signals from the sensors. Each sensor is an ionic liquid sensor tuned for sensing a smell associated with a chemical species. The processing circuit further includes an artificial intelligence engine to enhance smell recognition capabilities of the device.
