Thermoelastic damping in microbeam resonators with a proof mass

  Predicting thermoelastic damping is crucial for the design of high Q MEMS devices.In thepast,for the thermoelastic damping in microbeam resonators,Zeners model (1937 Physical Review 52 230-5; 1938 Physical Review 53 90-9) and Lifshitz and Roukes model (2000 Physical Review B 61 5600-9) can give a reasonable prediction.However,the derivations of Zeners model and Lifshitz and Roukes model are only suitable for a simple beam with no proof mass.The microbeam with a proof mass is a common element in many MEMS devices.In this paper,a general proof is presented that shows LRs model is also valid for the TED in the microbeams with a proof mass.The derivation in this paper is based on a general case.
