Synthetic Implants with Controlled Immune Response

­ Executive Summary Polymers such as polylactic acid (PLA) are commonly used as bioabsorbable materials for implants. Unfortunately, degradation products from these often promote adverse host immune responses in patients, which may require a secondary medical intervention such as surgery to remove the implant. To attempt to counter this, some...

Method and Apparatus for Autonomous Self-Powered Integrated Piezo-Floating Gate Sensors

IntroductionEach year, hundreds of thousands of hip and knee replacement surgeries are performed in the United States. Most of these prosthetic implants are expected to last for at least 20 years after which revision and replacement surgery will be required. In many cases, however, excessive wear and loosening of artificial joints leads to joint swelling,...
