Abstract
Chemical sensors and methods of using and making the same include a functionalized electrode configured to change surface potential in the presence of an analyte. A piezoelectric element is connected to the functionalized electrode and is configured to change in volume in accordance with the surface potential of the functionalized electrode. A piezoresistive element is in contact with the piezoelectric element and is configured to change in resistance in accordance with the volume of the piezoelectric element.
