摘要: 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.

摘要: A piezoelectric Micro-Electro-Mechanical Systems (MEMS) device comprising: a physical element; and a piezoelectric sensor element, with the physical element positioned in proximity to a moving portion of the piezoelectric sensor element, and with proximity of the physical element to the moving portion reducing a probability of breakage of the piezoelectric sensor element by limiting an excursion of the piezoelectric sensor element, relative to a probability of breakage of the piezoelectric sensor element in another piezoelectric MEMS device without the physical element.

摘要: An acoustic sensor has a MEMS die with MEMS structure. Among other things, the MEMS structure includes a diaphragm configured to mechanically respond to incident acoustic signals, and a temperature sensor member configured to detect temperature.
