This paper describes the capacitive pressure sensor design for biomedical applications like blood pressure measurement. The described pressure sensors provide high sensitivity even at low pressure range suitable for biomedical applications. Effects of varying different parameters on the pressure sensor performance have been studied. From the results, the pressure sensors with compatible parameters can be selected for specific requirements. These compact pressure sensors are made up of biocompatible materials and can be implanted easily inside body to be used for RF telemetry purpose
