Packaging Method to Maintain Signal to Noise Ratio in Implantable Sensors

Summary

Researchers at Purdue University have developed a packaging method to reduce drift in implantable pressure sensors. The approach encloses the sensor in a medical balloon that is filled with silicone oil and sealed with UV epoxy around a polyimide cable that carries the sensor. The sensor is isolated from bodily fluids while the balloon and oil transmit the surrounding pressure to the sensor. This method provides easier implementation, low cost, and increased versatility in comparison to currently available technologies in the market place.
