Resonating MEMS biosensors

Research topics >>


Transfer printing, a technique that is used to transfer diverse materials from DNA molecules or photoresist, to semiconductor nanowires, has been proven useful for the fabrication of various static and mobile structures under the name of micro-masonry. Here, we introduce a simple and straightforward fabrication process based on micro-masonry to realize nanoplate resonators with integrated electrostatic actuation and capacitive detection in a few steps. This approach is an alternative solution to the current fabrication methods used to create membranes and plates that usually rely on the selective etching of a sacrificial layer or the backside of a silicon wafer. Because the cavities used for electrostatic transduction are tight sealed, nanoplates fabricated via micro-masonry are suitable for liquid environment operation and are thus a promising solution for biosensing applications.
