Design and optimisation of NiTi pressure gauge

Abstract

This paper describes construction of a NiTi pressure gauge for possible application mostly in an automotive. The aim of our work is to present different data of an electrical properties of the pressure gauge. These data are strongly dependent on several input variables - for example the mechanical stress and the temperature of surrounding environment. Next aim of this paper is to describe development of the software which was designed for optimisation of the sensor shape. This is necessary to reach expected force range, to ensure that maximal allowed strain would not be exceeded and to come up with an optimal solution of compensation of sensors resistance temperature drift and nonlinearities.
