Two systems of the on-chip signal processing for hand held chemical agent sensors have been investigated. The principle of one on-chip signal processing is dependent on the resistance changes of the chemical sensor or chemical materials. The other principle is dependent on the impedance test. One prototype was built and delivered. The other three prototypes can be demonstrated. Two detectionamplification concepts were explored. The resolution of the relative resistance measurement is better than 10 to the minus 6th power. Suggestions for the future development are proposed.
