    摘要: A pressure sensing device and method for sensing pressure utilizes a deformable cavity containing a conductive medium. Pressure changes induce deformations of the cavity, resulting in changes of conductivity, as measured by electrodes. The device may either sense pressure directly or may be used to sense the pressure in a separate cavity that is in close proximity. Since the measurements do not require electrodes in the sensing region, the device is simple to fabricate. The device also has high sensitivity, making it suitable for microfluidic or biomedical applications where a low profile and disposable device is required.
