会议名称:European Frequency and Time Forum and International Frequency Control Symposium (EFTF-IFCS 2017)
会议时间:9-13 July 2017
会议地点:Besancon, France
会议简介:The 31st European Frequency and Time Forum and the 71st consecutive meeting of the IEEE International Frequency Control Symposium will be held as a joint conference in Besançon, France, July 9th-13th 2017. The conference will provide information on recent advances and trends on scientific research, development and manufacturing technology in the area of frequency and time and frequency control. A technical exhibition will be held during the conference, which will be hosted in Micropolis Conference centre, easily reached by ground transportation from downtown Besançon. Scenic city and historic capital of the french horology, Besançon can easily be reached by high speed train from Paris and by car or regular trains from Lyon, Basel or Geneva. The European Frequency and Time Forum (EFTF) was born in 1987 in Besançon, a wonderful small city 400 km south east from Paris.

Title: Effect of Joule Heating on the Performance of a Piezoresistive Micromechanical Oscillator
Author: Liu Xu, Xueyong Wei*, Dong Pu, Zhuangde Jiang
Abstract: Piezoresistive sensing has been regarded as an effective transduction method in MEMS research and piezoresistive micromechanical oscillators are therefore of great interests. The induced joule heating in the piezoresistive sensing, however, has a strong effect on the performance of the device. In this work, a micromechanical double ended tuning fork (DETF) based piezoresistive oscillator was studied. The results show the oscillation frequency drifts and the frequency stability decreases when the resonator body temperature increases due to Joule heating.  A linear relationship between the minimum Allan deviation and the piezoresistive current is observed from the experiment.
