There is provided a system and method of selectively monitoring ions in a fluid medium using a graphene sensor, the method comprising the step of adjusting an operating frequency of the graphene sensor to a particular resonant frequency for targeting resonance of specific ions in the fluid medium. In the proposed method, dispersive effect of the fluid medium is used to tune the graphene sensor to a desired frequency, thereby obtaining resonance response for specific ions in the fluid medium. Also, the monitoring of a specific ion in the fluid medium is unaffected by presence of a plurality of other ions in the said fluid medium.

System and method for selective ion monitoring

Electrical Tomography (ET) Images of an object can be generated based on features extracted during an excitation cycle. For example, a method described herein can include selecting, from a plurality of electrodes attached to the object, a first pair of electrodes. The method can include exciting the first pair of electrodes during a first excitation cycle. Additionally, the method can include generating an analog signal by performing measurements across remaining pairs of electrodes of the plurality of electrodes during the excitation cycle. The method can include generating the digital signal based on an analog to digital conversion of the analog signal. Further, the method can include extracting, during the excitation cycle, features based on the digital signal. The method can include generating an ET image associated with the object based on the features.
