Abstract
An illustrative humidity sensor may include a substrate and a sensing field effect transistor. The sensing field effect transistor may comprise a source formed on the substrate, a drain formed on the substrate, a gate, and a piezoelectric layer disposed over the gate. Another illustrative humidity sensor may comprise a substrate, a semi-conductor layer disposed over the substrate, a piezoelectric layer disposed over the semi-conductor layer, a first electrode disposed on the piezoelectric layer, and a second electrode disposed on the piezoelectric layer. In some instances, the piezoelectric layer may comprise aluminum nitride.
