Abstract: A novel attempt was made to develop a multifunction sensor using piezo resistive material for sensing pressure and temperature simultaneously as because it is well known that piezo resistive material has better selectivity to both temperature and pressure or force variables. The advantage of use of piezo resistive material is that it occupies minimum space. The aggregated output, when excited by electrical signal varies with respect to temperature and pressure both. From the output, the temperature and pressure values are extracted with developed model using multiple regression technique and artificial neural network.


Keywords: Multiple linear regression, Piezo-resistive sensor, Radial basis network
