  • Fine particle sensor with cascaded microscales
    Patent number: 11841306
    Abstract: A sensor for the continuous in-situ analysis of an aerosol flow for measuring the mass of the micron/submicron particles suspended in the air flow, including an aeraulic sorter allowing the particles to be sorted according to their size with an impactor body with a cascade of one or more stages; at least one MEMS microbalance per stage, with an oscillating silicon membrane located on the impaction zone of the particles; processor connected to each MEMS microbalance to determine the mass of all the particles on the impaction zone; a system for cleaning the MEMS microbalances allowing the evacuation of the particles from the MEMS microbalances; means for driving the aerosol flow.
    Type: Grant
    Filed: August 30, 2019
    Date of Patent: December 12, 2023
