A silicon pressure microsensor fabrication process is reported. The microsensor has been designed as a low-cost disposable device for invasive blood pressure measurements. Results obtained from static, dynamic and leakage pressure tests are presented. A sensitivity of has been measured. The combined linearity and hysteresis is less than 1.5% FSO. The dynamic response is fast enough to reproduce the blood pressure waveform of the human heart. Results based on a material biocompatibility study are also included.
