Abstract: A robust MEMS transducer includes a kinetic energy diverter disposed within its frontside cavity. The kinetic energy diverter blunts or diverts kinetic energy in a mass of air moving through the frontside cavity, before that kinetic energy reaches a diaphragm of the MEMS transducer. The kinetic energy diverter renders the MEMS transducer more robust and resistant to damage from such a moving mass of air.
