The Performance of the Output Signal of Micro Switch Group Sensor (MSGS)

is the ability to fabricate a large number of small devices economically. However such devices tend to have errors caused by the variations of fabrication and inherent noise signals such as Brownian motion or Johnson noise. This paper advances the understanding of Micro Switch Group Sensors (MSGS). In this paper, a MSGS comprising of 20 switches has been built using electronic circuits and tested to verify the performance. The output signal is compared to the number of switches turned on and analysed. The fluctuations of the output signals and the measured performance of the electrical circuit was shown to be in good agreement with the theoretical prediction. The output signal is compared to the input signal and shows that MSGS has been successfully applied as a measurement tool. Moreover the possible measurement range by using the MSGS is defined as the function of the number of switches.
