Robust micromachining thermal mass flow sensor and method of making the same

Abstract

The present invention is generally related to a novel micromachining thermal mass flow sensor and, more particularly, to a device incorporated with high strength and robust characteristics, which therefore is capable of operating under harsh environments. The new disclosed sensor is made of essential material which can provide robust physical structure and superior thermal properties to support the flow measuring operation. The invented thermal mass flow sensor is featuring with the advantages of micro-fabricated devices in terms of compact size, low power consumption, high accuracy and repeatability, wide dynamic range and easiness for mass production, which could avoid the drawbacks of fragility and vulnerability.
