| Abstract: | In this work, a new structure design of micromechanical inclinometer is presented. It consists of two silicon bulk masses that are connected by two parallel silicon beams. The two beams are in the same sizes and located symmetrically between the two masses, thus improving the lateral shock resistivity. The quantitative expression of stress distribution on the two beams versus tilting angle has been derived, and calculated results have been discussed. Finally, the process procedure of fabricating such a inclinometer is proposed. |
