It uses a Faraday cup with a floating electrode inside, which is connected to the gate of a MOS like transistor. The SOI based technological realization allows a new degree of freedom for more flexible measurements as compared to conventional FET based transducers. Potentiometric measurements are presented. Additionally the SOI technology allows simple packaging.enCharge sensitive fluid sensor for chemical and biological applicationsconference paper
