Abstract:
1. An RF MEMS based biosensor with two sensing modes comprising: a) a non conductive substrate; b) parallel, spaced-apart electrically conductive ground lines situated atop said substrate; c) a bottom electrode comprising a conductive signal line positioned between said spaced-apart ground lines, said signal line aligned in parallel to said ground lines; d) a dielectric layer which covers said signal line; e) a top electrode comprising a flexible rectangular membrane having a top surface and a bottom surface, said membrane suspended above a portion of said dielectric layer covered signal line so as to define a gap between them, said flexible membrane at each end supported by and in electrical contact with said spaced apart ground lines; and, f) a coating of biorecognition elements disposed on said dielectric layer covered signal line, and the top surface of said flexible membrane.
