Implantable Pressure Sensor with Integrated Guyton Chamber
- Summary
- Researchers at Purdue University have developed an implantable pressure sensor that eliminates the interaction of cells and other biological materials with the sensor. This sensor uses an integrated Guyton chamber that separates the pressure sensor from the surrounding cells and biomolecules. Thus, in vivo pressure can be monitored for a much longer time than current methods while maintaining high accuracy. This method can be used for several types of sensors including capacitive and piezoresistive sensors.

- *Abstract
-
- *Background
- Monitoring in vivo pressure is a critical element in many medical applications including cancer and glaucoma treatment. However, the interaction of biological materials with pressure sensors leads to sensor drift, which causes the pressure sensors to become highly inaccurate and lose sensitivity after a short time.
