USPTO Abstract
The invention relates to a vibrating mesh module for use in an aerosol-generating device, comprising a MEMS membrane with a plurality of through-holes to define perforations of the membrane, and a flow chamber located adjacent to the MEMS membrane, wherein the flow chamber defines a volume configured for holding aerosol-forming substrate and for feeding the aerosol-forming substrate to the MEMS membrane. The invention also relates to an aerosol-generating device comprising such vibrating mesh module. The invention also relates to a method of manufacturing a vibrating mesh module for use in an aerosol-generating device, the method comprising manufacturing a membrane from a bulk wafer of a first material using MEMS techniques, manufacturing a flow chamber from a bulk wafer of a second material using MEMS techniques, attaching the flow chamber to the membrane to form the vibrating mesh module.
