Bioinspired early detection through gas flow modulation in chemo-sensory systems
(2015-01-01)
Article
Open AccessThe design of bioinspired systems for chemical sensing is an engaging line of research in machine olfaction. Developments in this line could increase the lifetime and sensitivity of artificial chemo-sensory systems. Such ... -
Calibration transfer and drift counteraction in chemical sensor arrays using direct standardization
(2016-05-18)
Article
Open AccessInherent variability of chemical sensors makes it necessary to calibrate chemical detection systems individually. This shortcoming has traditionally limited usability of systems based on metal oxide gas sensor arrays and ... -
Canine-inspired unidirectional flows for improving memory effects in machine olfaction
(Oxford University Press, 2023-08-23)
Article
Open AccessA dog's nose differs from a human's in that air does not change direction but flows in a unidirectional path from inlet to outlet. Previous simulations showed that unidirectional flow through a dog’s complex nasal passageways ... -
Chemical sensor systems and associated algorithms for fire detection: A review
(Multidisciplinary Digital Publishing Institute (MDPI), 2018)
Article
Open AccessIndoor fire detection using gas chemical sensing has been a subject of investigation since the early nineties. This approach leverages the fact that, for certain types of fire, chemical volatiles ... -
