Abstract: Disclosed embodiments may relate generally to a micro airflow generator which does not use fan(s) or a heater to generate airflow (for example in a compact optical PM sensor). Rather, disclosed embodiments typically may use induced movement of a membrane/diaphragm element to generate air flow (wherein movement of the membrane in turn induces movement in air). For example, a membrane or diaphragm element could be driven by an (electronic) actuator element, such as an electro-magnetic actuator or piezo disc bender (or some other means of vibrating/moving the membrane element in a way which induced airflow). In some embodiments, the electro-magnetic actuator itself may include a membrane (such that the electro-magnetic actuator might encompass the membrane and the electronic actuator element, such as a magnet and corresponding coil) and/or the piezo disc bender might serve as both the membrane/diaphragm and the electronic actuator element.
