Abstract

See full text

Methods of using and making chemical sensors include exposing a functionalized electrode to a substance to be tested. The functionalized electrode is electrically connected to a sensor having a piezoelectric element and a piezoresistive element. A voltage on the functionalized electrode controls a resistance of the piezoresistive element. A current is measured passing through the piezoresistive element. The presence of the analyte is determined based on the measured current.
