Signal-to-Noise Enhancement of a Nanospring Redox-Based Sensor by Lock-in Amplification
A significant improvement of the response characteristics of a redox chemical gas sensor (chemiresistor) constructed with a single ZnO coated silica nanospring has been achieved with the technique of lock-in signal amplification. The comparison of DC and analog lock-in amplifier (LIA) AC measurement...
