A simple implantable pressure transduction system consists of a pressure-sensing element with a method to transmit the data to an external unit. The biological environment presents a host of engineering issues that must be considered for long term monitoring. Therefore, the design of such systems must carefully consider interactions between the implanted system TI - Chronically Implanted Pressure Sensors: Challenges and State of the Field JF - Sensors DO - 10.3390/s141120620 DA - 2014-10-31 UR - https://www.deepdyve.com/lp/unpaywall/chronically-implanted-pressure-sensors-challenges-and-state-of-the-4kf81x0vi5 DP - DeepDyve ER -
