Pressure sensors are vital to a number of applications. They are required in many sectors and their use is gaining popularity. MEMS pressure sensors can be either capacitive or piezoresistive. Capacitive pressure sensors provide a higher level of sensitivity and are also more temperature-independent. However, piezoresistive sensors provide high linearity and stability. Currently, the most common MEMS pressure sensor uses a deformable diaphragm. The diaphragm can be made of silicon or other material. When bonded to an optical fiber, the diaphragm can form a Fabry-Perot cavity.
MEMS pressure sensors are also being used in invasive applications, such as catheter tip sensors. Some biomaterials are being investigated for their functional capabilities. Another example is a glucose sensor that is fabricated on a miniaturized MEMS cell.
