Gore MEMS is a family of protective vents from W. L. Gore & Associates that protect Micro-Electro-Mechanical Systems (MEMS) devices like microphones from the intrusion of environmental contaminants such as dust and moisture. The microphones normally use these vents to balance the air pressure inside and outside both ends of MEMS mic cavity so that its very sensitive acoustic performance is stable during MEMS mic working, and some passive shock absorbing layers on the MEMS chip are made based focused on these vents in order to make MEMS microphone more durable while applied in smartphones, smart watch or other consumer devices. Gore MEMS protective vents leverage an expanded polytetrafluoroethylene (ePTFE) membrane that is hydrophobic and oleophobic to prevent dust and moisture ingress while allowing sound waves through. Protecting sensitive MEMS components while meeting device acoustic performance and form factor requirements is a challenge; hence, this technology is crucial.
