In this paper a new piezoresistive flow-meter has been proposed. For enhancement of sensitivity, a large membrane is placed vertically against the flow direction to maximize the air drag force. In the new proposed structure supporting beams do not scale up the total die-size, and due to large torsion spring constant, considerable incensement in mechanical stability is achieved. The range of measureable flow is 0-6m/s, and maximum variation of piezoresistors is 3.6 percent. Bulk micromachining technology is proposed for fabrication process and total die-size of flowmeter is 1.5×1.5 mm2.
