microventing
Microventing refers to the controlled release or exchange of gases or vapors through miniature openings or porous materials. It describes low-flux venting aimed at maintaining pressure balance, humidity control, or vapor management in sealed or semi-sealed systems while limiting energy loss, contamination, or ingress of dust and liquids. The concept is applied across disciplines, from electronics packaging to building materials and microfluidics.
Technologies and mechanisms used in microventing include diffusion through microporous membranes, microchannel vents, and capillary or
Applications span multiple industries. In electronics and automotive sensing, microventing can relieve internal pressure or humidity
Advantages of microventing include improved pressure equalization, reduced moisture-related issues, and targeted vapor transport. Limitations involve
