Abstract :
This paper describes a new low-cost electronic interface to process signals generated by capacitive sensors. Design criteria and accuracy evaluation have been presented by means of a theoretical apparatus. Extended experimental tests confirmed these results showing the excellent ratio between performance and costs of the system. Specific applications of this work can be found in extended arrays of sensing elements typical of robotic applications
