A chemiresistor is a material that changes its electrical resistance in response to changes in the nearby chemical environment. Chemiresistors are a class of chemical sensors that rely on the direct chemical interaction between the sensing material and the analyte. The sensing material and the analyte can interact by covalent bonding, hydrogen bonding, or molecular recognition. Several different materials have chemiresistor properties: metal-oxide semiconductors, some conductive polymers, and nanomaterials like graphene, carbon nanotubes and nanoparticles. Typically these materials are used as partially selective sensors in devices like electronic tongues or electronic noses.
Method for manufacturing oxidized mxene and chemimemristor device using the same
A method for manufacturing oxidized MXene according to a preferred embodiment may remove fluorine groups (F) on a surface of MXene and form OH functional groups through an oxidation process to effectively adsorb CO2 molecules and reversibly change electrical conductance according to gas concentration. In addition, a chemimemristor device based on the oxidized MXene (Mn+1Xn(OH)2) may simultaneously implement memristor and gas sensor functions in a single device, and maintain multiple levels of conductance depending on the concentration of adsorbed molecules, and implement, based thereon, reversible changes in conductance according to a concentration of CO2 and multi-level information processing through its characteristics of learning multi-level operations and molecular adsorption history to mimic the human sense of smell and synaptic plasticity of the brain.
