STRAIN COMPENSATION FOR PRESSURE SENSORS |
摘要 |
An implantable medical sensor system provides signals representative of a magnitude of moment fraction applied to a sensor module at a selected site. A sensor module includes a first transducer producing a first signal having an associated first response to pressure and strain applied to the sensor module and a second transducer producing a second signal having an associated second response to pressure and strain applied to the sensor module. A moment fraction is computed in response to the first signal and the second signal. In various embodiments, the moment fraction is used to guide positioning of the sensor module, indicate a need for repositioning the sensor module, report loading of the sensor module during normal operation for use as sensor design information and in setting sensor calibration ranges. |
