Scientists have developed a tiny, implantable, self-powered, wireless transmitter chip for monitoring and treating glaucoma patients and other biomedical applications.
Irazoqui said a lot of medical treatments operate in an open loop. "You take antibiotics, but no one is measuring their effectiveness," he said. "What you really want to know is how the body is responding in real-time."
Having an implanted device that can report biomedical data and apply a therapeutic response closes that loop, he suggests.
Rather than relying on a battery, which isn’t something people want in their bodies, the transmitter harvests power by converting radio frequency waves into direct current, using cavity-resonator based magnetic resonance coupling.
