Abstract: A sensor device for measuring a flow of a fluid. The sensor device can have a support structure and a sensing structure. The support structure can have an elongated shape; can be flexible; can comprise steel, tungsten, carbon nanomaterial, polymer or plastic; can have multiple sides with sensing structures on each side; and can have a rectangular or square cross-section. A plurality of the sensor devices can be adapted for use on a surface of a vehicle or a microelectronic device. A plurality of sensing structures can be provided in any suitable configuration on the support structure. The sensor device can have any suitable shape, preferably similar to a flexible whisker. The sensing structure can be formed using a semiconductor etching method. Also, a method for manufacturing the sensor device and a computer method, system and software related to the sensor device are described.
