Latest Patents

Rodolf Herfst holds a patent for an RF MEMS switch featuring a grating as a middle electrode. This invention provides a capacitive MEMS device that includes a first electrode lying in a plane and a second electrode suspended above it. The first electrode serves as an actuation electrode, while a gap exists between the first and second electrodes. A third electrode is positioned between the first and second electrodes, with a gap separating it from the second electrode. This third electrode incorporates one or more holes, which can be arranged in an orderly or irregular pattern. The integration of a conductive grating as a middle electrode offers the advantage of independent control over the pull-in and release voltage of the switch, effectively reducing issues present in prior art.
