A recent Phys.org article noted a novel type of implantable sensor developed at Johannes Gutenberg University Mainz that employs gold nanoparticles to solve the issues of current sensors. The problem with implantable sensors that continuously transmit information on vitals is that they can’t remain in the body for more than a few weeks. Either the immune system rejects the device, or the sensors that use color to indicate concentration changes fade over time.
