Through researching an elastic sensitiveelement, a bellows with filler has been designed and developed, which solved the difficult problem that a thin wall bellows can't withstand high pressure.
The micro gas pressure sensor designed in this thesis can be fabricated using an IC compatible process, and it is composed of a heating resistor, a sensitiveelement and a testing resistor.
