Abstract
A MEMS chip for wind speed measurements is provided. The chip integrates one or multiple embedded channels and a pressure sensor. The pressure sensor consists of a sensing membrane with a cavity beneath it. Each channel has one end connects to the cavity while the other end opens on the edge of the chip. To measure the wind speed, the membrane faces the wind and the air stagnates onto it while the channel connects the cavity to the static pressure. And the membrane deforms according to the wind pressure. The wind speed is then derived from the measured wind pressure.
