Abstract:
Disclosed is a MEMS sensor including a sense element and a single anchor that supports the sense element arranged in a central hub-like fashion that reduces the effects of thermal stress. Usually, two or more anchors are required to suitably constrain the sense element's motion. The anchor disclosed herein, however, supports the sense element with connection elements having a connection geometry that substantially limits the motion of the sense element to a single-degree-of-freedom. The connection elements may include, for example, converging flexures, an extender bar, or both.
