Electronic Rape Technology Pressure Sensor Electronic rape is being accomplished with ultrasound or RF stimulated pressure (most likely ultrasound because it causes pressure) between pressure sensors. There will be more information next week. We ran out of time for a more complete discussion. Chronically Implanted Pressure Sensors: Challenges and State of the Field Abstract: Several conditions and diseases are linked to the elevation or depression of internal pressures from a healthy, normal range, motivating the need for chronic implantable pressure sensors. 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 and the body, including biocompatibility, surgical placement, and patient comfort. Here we review research developments on implantable sensors for chronic pressure monitoring within the body, focusing on general design requirements for implantable pressure sensors as well as specifications for different medical applications. We also discuss recent efforts to address biocompatibility, efficient telemetry, and drift management, and explore emerging trends.
