20140069232 | MOTION CONVERSION MECHANISMS - A mechanism and method for motion conversion is disclosed. This mechanism can be easily fabricated using standard bulk micromachining technology. Based on this method with appropriate design, a horizontal, in-plane motion can be converted to a vertical or angular displacement out-of-plane. This design has great advantages in micro devices, which are built from a single layer, i.e. wafer fabrication, where an in-plane force is easy to implement, such as by the use of comb drive mechanisms, but an out-of-plane motion may be hard to achieve. The mechanism comprises a pair of beams of different heights, rigidly connected together at a number of points along their length, such that application of an in-plane force to the double beam structure results in out-of-plane motion of the double beam structure at points distant from the point of application of the force. | 03-13-2014 |
