A Platform for Nanomaterial-Enhanced Gas Sensing using Magnetomotive MEMS

  • Author / Creator

  • We present a platform for research into nanomaterial-enhanced gas sensing using magnetomotive MEMS resonators. A microfabrication process fl ow is developed and carried out to create metallized silicon MEMS resonators. In tandem, a test system based around a balanced electronic bridge is constructed to perform full electrical characterization of our devices, both in atmosphere, and at vacuum. An innovative fine-tuning circuit allows this apparatus to be built at low-cost. Initial results, compared with predictions from modelling, reveal that our system works as intended, but further optimization of our devices is required to achieve the best possible performance.
