    Abstract: A microphone structure of an MEMS device has a layer construction including: a base substrate; a deflectable microphone diaphragm at least partly spanning a through-opening in the substrate; a deflectable electrode of a microphone condenser system; a stationary counter-element having ventilation openings situated in the layer construction over the microphone diaphragm and acting as a bearer for a stationary electrode of the microphone condenser system. The diaphragm is bonded into the layer construction on the substrate via a flexible beam. The otherwise free edge region of the diaphragm is curved in a pan shape, so that it extends both vertically and also in some regions laterally beyond the edge region of the through-opening, and the edge region of the through-opening forms a lower stop for the diaphragm movement.

    Abstract: A compliant mechanism includes a body that is configured to generate a mechanical output in response to a mechanical input. The body has at least one region formed by an active material. The compliant mechanism also includes at least one activation device configured to selectively apply an activation signal to the at least one region. The active material is configured to undergo a change in modulus in response to the activation signal such that the output is characterized by a first magnitude or direction when the activation device applies the activation signal and a second magnitude or direction when the activation device does not apply the activation signal.
