摘要 |
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for making and using accelerometers. Some such accelerometers include a substrate, a first plurality of electrodes, a second plurality of electrodes, a first anchor attached to the substrate, a frame and a proof mass. The substrate may extend substantially in a first plane. The proof mass may be attached to the frame, may extend substantially in a second plane and may be substantially constrained for motion along first and second axes. The frame may be attached to the first anchor, may extend substantially in a second plane and may be substantially constrained for motion along the second axis. A lateral movement of the proof mass in response to an applied lateral acceleration along the first or second axes may result in a change in capacitance at the first or second plurality of electrodes. |
