In this work, resonant microcantilever sensor is firstly used for real-time record of gas uptake on sensing material to extract the key kinetic parameter of activation energy (Ea), which characterizes molecule adsorbing rate. With the extracted parameter of Ea, the important gas sensing performance of response speed can be quantitatively evaluated with theory of molecule sorption kinetics and optimally...
A novel method is explored for comprehensive design/optimization of organophosphorus sensing material, which is loaded on mass-type microcantilever sensor. Conventionally, by directly observing the gas sensing response, it is difficult to build quantitative relationship with the intrinsic structure of the material. To break through this difficulty, resonant cantilever is employed as gravimetric tool...
