Two cases are investigated using analytical methods: uniform temperature distribution and linear temperature distribution along the length of the sensor. It is found that the thermal frequency drift is dominated by the temperature-dependent material properties. Thermal frequency drift also depends on the ratio of the thickness of the gold coating and the thickness of the silicon cantilever. The results show that the relationship between thermal frequency drift and the ratio of gold-to-silicon thickenss is nearly linear. |  | View paper | | ISBN: | 0-9708275-0-4 |
