Piezoelectric air pump
8 February 2012
Passive Components
Murata announced the MZB1001 microblower, a miniature piezoelectric air pump designed for a wide range of household consumer products. Measuring 20 x 20 x 1,85 mm (excluding nozzle), it is believed to be the smallest air pump in the market.
Using a piezoelectric diaphragm which vibrates up and down when a sine wave voltage is applied, the vibrations force air into the microblower and out through a nozzle on the top of the device. The device can produce typical airflow rates of up to 0,8 litres per minute and typical air pressure up to 1,5 kPa when driven by a 15 Vp-p, 25 kHz signal. The piezoelectric diaphragm has been optimised for operation above the normal audible range and is typically driven by a 24–25 kHz signal.
Used as an air pump and capable of creating a high air pressure flow, the microblower is ideally suited to short duration, high-pressure airflow applications. The piezoelectric diaphragm typically consumes only 0,2 W. Typical applications include aromatic atomisers, air fresheners and other similar household fragrance products.
