hii

I am working in design MEMS based piezoresistive pressure sensor .we are using intellisuite software for the design of the pressure sensor .The pressure sensor is a rage of 0 to 500

I like to kown about wheatstone bridge circiut in the sensor how much resistance we have to us for the pressure range of 0 to 500

Hi

Let me clarify my understanding about piezoresistive pressure sensor. The amount of pressure applied to cause a change/ deformation corresponds to the change in resistance , is that right?

Maybe the attached file would help.

Hi Kevin
what you said is correct .when we apply a pressure the resistance in the Wheatstone bridge changes.

Thank you for your replay
