Abstract :
Based on resonant-cantilever adsorbing experiment, a set of key thermodynamic/kinetic parameters of gas sensing materials is quantitatively extracted for overall performance assessment among sensitivity, repeatability and speed. With the method, individual optimization for carrier-structure and sensing-group of organophosphate sensing material is achieved for sensing-performance synergistic improvement.
