摘要：

We have developed a MEMS power conversion device that combines an axial-flow turbine with an axial-flux electromagnetic generator. This device can generate electrical power when placed in an air-stream, and is aimed at applications such as flow sensing and power generation for remote sensors. Recent experimental performance data are presented for prototypes, and compared with CFD (computational fluid dynamics) simulations. The current devices have a volume of approximately 0.5 cm(3) generate 1 mW of output power at a pressure drop of 8 mbar and a flow rate of 35 litres per minute, and will operate at pressure drops down to a few mbar.
